Melting pennies down is illegal under federal law, and the prohibition applies to both the shiny zinc pennies in your pocket today and the older copper ones. A 2006 Treasury Department regulation specifically bans melting pennies and nickels, and older criminal statutes add additional legal exposure for anyone who tries.
Most people assume this is one of those obscure laws that nobody enforces. That assumption is mostly right in practice, but the law is clear and the penalties are real.
This guide covers exactly which laws apply, what the penalties are, whether pre-1982 copper pennies change the picture, and what related activities like defacing coins and melting nickels actually mean legally in 2026.
Is It Illegal to Melt Pennies Down
Melting pennies down is illegal under federal law. The US Treasury Department’s regulation at 31 C.F.R. Part 82, published in December 2006, specifically prohibits the melting, treatment, or export in bulk of pennies and nickels.
The regulation was a response to a practical economic problem. In 2006, the price of copper and zinc rose to the point where the metal in a penny was worth more than one cent. The Treasury acted to prevent the penny and nickel from being systematically melted for scrap metal, which would reduce the coin supply and cost the government money to replace.
The prohibition covers both the physical act of melting and the intent behind it. The regulation targets industrial-scale melting operations, but its language applies broadly. A person who melts pennies in a home furnace for the purpose of extracting copper or zinc for resale has violated the regulation.
The practical enforcement picture is different from the legal picture. The US Mint and Treasury do not have inspection teams walking through garages. But the law is real, the violation is real, and the penalty is real.
Quick Facts:
- Federal regulation: 31 C.F.R. Part 82 (effective December 14, 2006)
- Coins covered: pennies (one-cent pieces) and nickels (five-cent pieces)
- Prohibited acts: melting, treating, or exporting in bulk
- Enforcement agency: US Mint, US Treasury Department
- Criminal statute also applicable: 18 U.S.C. 331
Is It Illegal to Melt Pennies
Yes, melting pennies is illegal under 31 C.F.R. Part 82 and can also trigger criminal liability under 18 U.S.C. 331 depending on the circumstances and intent involved. Both federal regulations are active and apply in 2026.
The 2006 regulation at 31 C.F.R. Part 82 is the more direct prohibition. It specifically targets pennies and nickels. It uses broad language to cover melting, treating to separate the metals, or exporting large quantities of coins.
The older criminal statute, 18 U.S.C. 331, predates the 2006 regulation and applies to anyone who fraudulently defaces, mutilates, impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the mints of the United States. Melting falls within “mutilates” when done with fraudulent intent to separate the metal value from the face value.
The two laws work differently. The 2006 regulation is administrative and creates civil liability. The criminal statute creates criminal liability for intentional fraud involving US coins. A person who melts pennies for their metal value could theoretically be charged under either or both, though criminal prosecution for small-scale individual penny melting has not been a documented enforcement priority.
| Law | Prohibition | Type | Year |
|---|---|---|---|
| 31 C.F.R. Part 82 | Melting/treating/exporting pennies and nickels | Administrative regulation | 2006 |
| 18 U.S.C. 331 | Fraudulent mutilation of US coins | Criminal statute | Longstanding |
| 18 U.S.C. 332 | Debasing coins | Criminal statute | Longstanding |
| 31 U.S.C. 5111 | Coinage Act provisions | Federal statute | Various |
Is It Legal to Melt Down Pennies
No, it is not legal to melt down pennies in the United States. The 2006 Treasury regulation at 31 C.F.R. Part 82 prohibits this specifically, and the federal criminal statute at 18 U.S.C. 331 provides an additional layer of legal prohibition.
Some people argue that they “own” their pennies and therefore can do whatever they want with them. That argument fails under federal law. The Coinage Act of 1965 (31 U.S.C. 5111) establishes that the government retains authority over how coins can be used, modified, and destroyed. Ownership of a coin does not override federal monetary regulations.
The analogy that works here is paper money. You own your dollar bills, but you cannot legally burn a stack of them with the intent of destroying the currency supply. The government’s interest in maintaining an adequate coin supply creates a public interest that overrides personal property arguments.
There are no legal exceptions for individuals who want to melt pennies for personal craft projects, artistic purposes, or home use. The regulation does not carve out a personal use exception. Artists who create works using melted coins do so in violation of federal law, though enforcement against such uses is essentially unheard of.
Quick Facts:
- Personal property argument: fails under federal monetary law
- Artist or craft exception: none exists under 31 C.F.R. Part 82
- Regulatory authority: US Treasury acting under Coinage Act
- Practical enforcement for individuals: extremely rare
- Legal status: clearly illegal under both regulatory and criminal law
Is It Legal to Melt Pennies
Melting pennies is not legal in the United States. Federal law prohibits it, and no state-level law creates an exception to the federal prohibition. This applies to all pennies in circulation regardless of their copper or zinc composition.
People who encounter information suggesting penny melting is a legal gray area are often reading outdated content from before the 2006 regulation was implemented. Before December 14, 2006, there was no specific regulation targeting penny melting. The older 18 U.S.C. 331 statute required a fraudulent intent element that made casual coin melting legally ambiguous. The 2006 rule removed that ambiguity.
The regulation is not subject to state variation. Federal monetary law preempts state law in this area. There is no US state where melting a US penny is legal, and no state has attempted to create such an exception because federal monetary law does not leave room for it.
The legal status is clear and simple: melting any US penny, for any reason, violates 31 C.F.R. Part 82 as it has been written since 2006. The enforcement reality is that the Treasury and US Mint focus on commercial-scale operations, not individuals, but the individual is still violating the law.
Key Takeaway: Melting pennies has been clearly illegal under federal law since December 14, 2006, when the Treasury implemented 31 C.F.R. Part 82. Before that date, only the fraudulent intent element of 18 U.S.C. 331 applied. Today, both regulations apply simultaneously and neither contains a personal use exception.
Is It Illegal to Melt Down Copper Pennies
Yes, melting down copper pennies is illegal under the same federal regulations that prohibit melting all pennies. The pre-1982 copper penny composition does not create a separate legal category or any exception to the prohibition.
Pre-1982 pennies, which contain approximately 95% copper and 5% zinc, have been worth significantly more than their one-cent face value in metal since copper prices rose sharply. A pre-1982 penny contains roughly 0.109 troy ounces of copper, and at copper prices in 2026, the metal value has periodically exceeded two to three cents per coin.
That financial incentive is precisely why the 2006 regulation was written broadly enough to cover all pennies without distinguishing between compositions. If older copper pennies were exempt from the melting ban, the regulation would have created an obvious workaround that defeated its purpose.
The 2006 regulation at 31 C.F.R. Part 82 applies to “pennies” as a category of US one-cent coins without any limitation based on composition or year of mint. A 1972 copper penny and a 2024 zinc penny are both covered by the same prohibition under federal law.
Quick Facts:
- Pre-1982 penny composition: approximately 95% copper, 5% zinc
- Post-1982 penny composition: approximately 97.5% zinc, 2.5% copper plating
- Legal status of melting either type: illegal under 31 C.F.R. Part 82
- Exception for copper content: none exists in the regulation
- Financial incentive: acknowledged by Treasury as the reason for the 2006 rule
Is It Legal to Melt Pennies for Copper
No, it is not legal to melt pennies for copper in the United States. Extracting copper from pennies through melting is specifically what the 2006 Treasury regulation at 31 C.F.R. Part 82 was designed to prevent, and doing so violates federal law.
The financial math makes the prohibition understandable. When the copper content of a pre-1982 penny exceeds one cent in market value, there is an economic incentive to melt them. If allowed, this would drain the supply of older pennies from circulation, increase the cost of producing replacement coins, and potentially destabilize the cent denomination as a functional currency unit.
Some people have sought legal ways to profit from high copper prices through pennies. Holding large quantities of pre-1982 pennies as a copper commodity investment is technically legal. Exporting them is not: the same 2006 regulation prohibits bulk export of pennies and nickels, which closes another potential loophole.
Selling pre-1982 pennies to coin collectors at a premium above face value is legal. Selling them to a scrap metal dealer for melting is illegal. That distinction, between the numismatic market and the scrap metal market, is where the legal line sits.
What is legal with pennies:
- Collecting pre-1982 copper pennies as a hobby or investment
- Selling pennies to coin dealers above face value (numismatic transactions)
- Keeping large quantities of pennies at home
What is illegal:
- Melting pennies for copper or zinc extraction
- Exporting pennies in bulk (more than $5 face value)
- Treating pennies to separate their metal content
- Selling pennies to scrap dealers for melting
Is It Illegal to Melt Old Copper Pennies Pre 1982
Melting old copper pennies from before 1982 is illegal under the same federal regulation that prohibits melting any US penny, and no exception exists for coins based on their age, composition, or collector status. The 2006 Treasury regulation applies to all pennies uniformly.
The pre-1982 distinction matters for numismatic and metal value purposes, but it does not create a legal distinction under federal monetary regulation. The Treasury has not issued any guidance suggesting that coins of a certain age or composition fall outside the prohibition.
Coin collectors who hold large quantities of pre-1982 pennies frequently ask whether there is a point at which old coins are treated as historical artifacts rather than currency. The short answer is no: a penny issued in 1965 is still legal tender and still subject to the coin melting prohibition as long as it is a US one-cent piece.
Pre-1933 gold coins and certain rare numismatic coins have specific legal frameworks that can affect their treatment, but ordinary circulation pennies from any year, including the early 20th century, remain subject to the same melting prohibition as a 2024 penny.
Quick Facts:
- Pre-1982 copper pennies: subject to same prohibition as all pennies
- Age exception: none exists in 31 C.F.R. Part 82
- Historical artifact status: does not apply to ordinary circulation pennies
- Composition exception: none, all penny compositions covered
- Numismatic transactions: legal, melting is not
Why Is It Illegal to Melt Coins
Melting coins is illegal because the US government has a vested interest in maintaining an adequate supply of currency in circulation, and allowing coins to be melted for metal value would undermine the coin supply, increase replacement costs, and potentially destabilize the monetary system.
The policy rationale behind the coin melting prohibition has three components. First, the government spends money producing coins, and allowing them to be destroyed for metal value means the government loses twice: once on production costs and again when it must produce replacement coins. Second, coin shortages disrupt commerce at the retail level in ways that inconvenience millions of people. Third, the integrity of the monetary system depends on coins functioning as currency rather than as raw material.
The 2006 regulation specifically cited rising metal prices as the trigger for the rule. When zinc and copper prices spiked, the US Mint calculated that the metal in a penny and nickel exceeded their face values, creating an economic incentive that the Treasury wanted to eliminate before it became a systemic problem.
The historical context matters too. The US has faced coin melting crises before. The silver content of pre-1965 dimes, quarters, and half dollars made them targets for melting when silver prices rose, leading to widespread coin shortages in the early 1960s. The Coinage Act of 1965 removed silver from circulation coins partly in response to this problem.
Key Takeaway: Melting coins is illegal because the government’s interest in maintaining a functioning currency supply overrides individual property rights to do whatever one wants with owned coins. The 2006 regulation was triggered by metal prices rising above face values, which created exactly the economic incentive the law is designed to eliminate.
What Does 31 CFR Part 82 Say
31 C.F.R. Part 82 is the specific federal regulation issued by the US Treasury Department in December 2006 that prohibits the melting, treatment, or export of pennies and nickels. It is the primary legal authority that makes penny melting clearly illegal in the United States.
The regulation states that no person shall melt, treat, or export United States coins composed of copper and zinc (pennies) or copper and nickel (nickels) except pursuant to license issued by the Director of the United States Mint. The language covers not just melting but any treatment that separates the metals or renders the coins non-functional as currency.
The export provision is a separate and important element. Exporting more than $5 face value in pennies or nickels without a license is also illegal under the same regulation. This provision was included because one potential workaround would be to export US coins to countries with lower labor costs where melting could be done more cheaply.
The penalty provision in the regulation provides for civil penalties up to $10,000 per violation and forfeiture of the coins involved. Criminal violations are addressed through the separate statutes at 18 U.S.C. 331 and 332. The regulation itself is an administrative rule, meaning it operates through civil enforcement rather than criminal prosecution.
Key provisions of 31 C.F.R. Part 82:
- Prohibition: melting, treating, or exporting pennies and nickels
- Exception: license from the Director of the US Mint (not available to individuals)
- Export limit: $5 face value per person per trip without license
- Civil penalty: up to $10,000 per violation
- Forfeiture: coins and any proceeds subject to government seizure
What Is the Penalty for Melting Pennies
The civil penalty for melting pennies under 31 C.F.R. Part 82 is up to $10,000 per violation, and violators also face forfeiture of the melted coins and any profits derived from the melting. Criminal prosecution under 18 U.S.C. 331 adds potential fines and up to five years in federal prison.
The two-track penalty system reflects the dual legal framework. Administrative violations of the 2006 Treasury regulation carry civil penalties enforced by the US Mint and Treasury. Fraudulent mutilation of coins under the criminal statute carries criminal penalties including prison time.
Under 18 U.S.C. 331, the criminal penalty is a fine under Title 18 and imprisonment of up to five years. The statute requires proof of fraudulent intent, which distinguishes casual melting from deliberate coin debasement. Someone melting pennies for copper profit demonstrates commercial intent that could satisfy this element.
The practical enforcement reality is that the Treasury and US Mint focus enforcement resources on commercial-scale operations, import of melted coin metals, and export violations. Individual hobbyists who melt small quantities of pennies are not known to have faced federal prosecution in documented cases. That enforcement pattern does not change the legal exposure, but it does contextualize the practical risk.
| Penalty Type | Source | Maximum Penalty |
|---|---|---|
| Civil fine | 31 C.F.R. Part 82 | $10,000 per violation |
| Forfeiture of coins | 31 C.F.R. Part 82 | All coins plus proceeds |
| Criminal fine | 18 U.S.C. 331 | Fine under Title 18 |
| Federal imprisonment | 18 U.S.C. 331 | Up to 5 years |
| Commercial scale penalty | Combined statutes | Enhanced based on volume |
Is It Illegal to Deface Coins
Defacing coins is illegal under 18 U.S.C. 331, which prohibits fraudulently altering, defacing, mutilating, imparing, diminishing, falsifying, scaling, or lightening any US coin. The key element is fraudulent intent, which distinguishes criminal coin defacement from minor incidental damage.
The deface prohibition covers more than melting. Stamping a logo onto a penny, pressing a design into it, drilling a hole through it for jewelry, or otherwise permanently altering its appearance can technically violate the statute. However, the fraudulent intent element has been interpreted by courts to require intent to use the altered coin as genuine currency or to profit through deception.
Pressed penny machines found in tourist attractions create stretched souvenir pennies that clearly alter their shape and appearance. These machines exist in legal commerce because the intent is clearly recreational or souvenir-oriented, not fraudulent monetary deception. The same logic applies to jewelry made from coins, though the legal basis for this common practice is technically the interpretation of “fraudulent intent” rather than a specific exception in the statute.
The practical guidance is that casual coin marking for identification purposes, souvenir pressing, and jewelry creation occupy a legally ambiguous but essentially unenforced space. Melting, on the other hand, has the explicit 2006 regulation creating a clearer legal prohibition.
Quick Facts:
- Defacement statute: 18 U.S.C. 331
- Key element required: fraudulent intent
- Souvenir pressed pennies: technically questionable but not enforced
- Coin jewelry: legally ambiguous, not prosecuted
- Deliberate fraud using altered coins: clear violation, actively prosecuted
Is It Illegal to Melt Nickels
Yes, melting nickels is illegal under the same 2006 Treasury regulation, 31 C.F.R. Part 82, that prohibits melting pennies. The regulation explicitly covers both the one-cent (penny) and five-cent (nickel) coins.
Nickels are covered because their metal composition, which is 75% copper and 25% nickel, made them even more valuable per coin in metal terms than pennies when metal prices peaked in 2006. The same economic incentive that threatened the penny supply applied to nickels, and the Treasury addressed both simultaneously.
The penalty structure for melting nickels is identical to that for melting pennies: up to $10,000 civil fine per violation under the 2006 regulation, plus potential criminal liability under 18 U.S.C. 331. The export restriction also applies: more than $5 face value in nickels cannot be exported without a US Mint license.
Nickels are worth considerably more in metal value per coin than pennies because the five-cent face value and relatively high copper and nickel content make the metal-to-face-value ratio more significant. This has led to active discussion in numismatic and precious metals communities about holding nickels as a commodity, which is legal, versus melting them, which is not.
Quick Facts:
- Nickel composition: 75% copper, 25% nickel alloy
- Legal status of melting: identical to pennies, prohibited under 31 C.F.R. Part 82
- Civil penalty: up to $10,000 per violation
- Export limit: $5 face value without a US Mint license
- Holding nickels as investment: legal; melting them: illegal
Is It Legal to Melt Foreign Coins
Melting foreign coins in the United States is generally legal because 31 C.F.R. Part 82 and the related US statutes apply specifically to US coinage. Foreign currency is not subject to US coin melting regulations.
The US has no federal regulation that prohibits the melting of coins issued by other countries. A person who acquires Canadian pennies, Mexican pesos, or any other foreign coin and melts them for metal value is not violating US federal law regarding coin destruction. The relevant laws of the issuing country would apply, not US law.
Some foreign countries do have their own coin melting prohibitions. Canada, for example, restricts the melting of Canadian coins under the Currency Act. Melting Canadian coins in the United States may not violate US law but could violate Canadian law if the melting is connected to activities in Canada or if the coins are then exported to Canada.
The practical implication for US residents is straightforward. Old Canadian pennies, British pennies, and other foreign coins made of copper or other metals can be legally melted in the United States for their scrap metal value. US pennies and nickels cannot.
Quick Facts:
- Foreign coin melting in the US: legal under US federal law
- US statutes covered: apply only to US-issued coinage
- Canadian coins: Canada’s Currency Act may restrict melting, but US law does not
- Metal content: foreign copper coins are legal scrap metal in the US
- Caution: check the issuing country’s laws for compliance in that jurisdiction
Is Melting US Coins a Federal Crime
Melting US coins is a federal violation, and it can be both a civil violation under Treasury regulations and a criminal federal offense under 18 U.S.C. 331. Whether it is prosecuted as a crime depends on the scale of the operation and the presence of fraudulent intent.
The civil regulatory violation under 31 C.F.R. Part 82 applies automatically to any melting of pennies or nickels, without requiring proof of criminal intent. The civil penalty of up to $10,000 per violation can be imposed by the Treasury without criminal prosecution.
The criminal federal offense under 18 U.S.C. 331 applies when there is fraudulent intent: the intent to defraud or deceive through coin alteration or destruction. A commercial operation that melts pennies to sell copper scrap, knowing the activity is prohibited, demonstrates the intent element that supports federal criminal charges.
Federal criminal prosecution for coin melting has occurred in cases involving large-scale commercial operations. Individual hobbyist cases are not part of the documented enforcement record. The Department of Justice and US Mint have limited enforcement resources and have focused them on commercial-scale violators.
Federal crime analysis:
- Civil violation: yes, automatic under 31 C.F.R. Part 82 for any melting
- Criminal offense: yes, under 18 U.S.C. 331 with fraudulent intent
- Criminal penalty: fines plus up to 5 years federal prison
- Enforcement priority: commercial scale operations over individual hobbyists
- Documented prosecutions: focused on commercial operations, not individual collectors
Frequently Asked Questions

Yes, melting pennies is illegal under federal law.
The Treasury Department’s regulation at 31 C.F.R. Part 82, effective December 14, 2006, specifically prohibits melting, treating, or exporting US pennies and nickels.
The criminal statute at 18 U.S.C. 331 adds additional legal exposure for fraudulent coin mutilation.
What is the penalty for melting pennies?
The civil penalty under 31 C.F.R. Part 82 is up to $10,000 per violation, plus forfeiture of the coins and any proceeds.
Criminal liability under 18 U.S.C. 331 carries fines and up to five years in federal prison for fraudulent coin mutilation.
Enforcement has focused on commercial operations rather than individuals, but the legal penalties apply to all violations.
Are pre-1982 copper pennies legal to melt?
No, pre-1982 copper pennies are not legal to melt. The same federal regulation that prohibits melting modern zinc pennies also prohibits melting older copper pennies.
31 C.F.R. Part 82 covers all US one-cent pieces without regard to their composition or year of issue.
Holding pre-1982 copper pennies as an investment is legal; melting them for their copper value is not.
Is it illegal to melt nickels too?
Yes, melting nickels is illegal under the same 2006 Treasury regulation that prohibits melting pennies.
31 C.F.R. Part 82 explicitly covers both one-cent (penny) and five-cent (nickel) coins.
The civil penalty and criminal exposure are identical to those for melting pennies.
Is melting foreign coins legal in the US?
Melting foreign coins in the United States is generally legal because US coin melting regulations apply only to US-issued currency.
31 C.F.R. Part 82 and 18 U.S.C. 331 cover only coins issued by the United States Mint.
However, the issuing country’s laws may independently prohibit the melting of their own coins, so checking those laws before melting foreign currency is worthwhile.
Closing
The legal picture on melting pennies is clearer than most people expect. It has been explicitly illegal under federal regulation since 2006, the penalties are real, and the older criminal statute adds another layer. The enforcement reality favors individual hobbyists in practice, but the law does not.
Bookmark this guide the next time someone insists that melting pennies is legal because you own them. The 2006 Treasury regulation settled that argument definitively, and it remains in full force in 2026.
