Can I find error coins in pocket change?
How Common Are Error Coins in Circulation?
Error coins are mistakes made during the minting process that slip past quality control and enter circulation. They are not common, but with billions of coins in circulation, some do get out. The odds of finding a significant error in your change are low—think one in thousands or tens of thousands of coins. Minor anomalies like slight off-center strikes or die cracks are more likely than dramatic errors like double denominations or wrong planchets.
- Off-center strikes: common enough to find occasionally.
- Die cracks and cuds: small defects on the die that transfer to coins.
- Broadstrikes: struck without a collar, so the coin is wider and thinner.
- Wrong planchet: a coin struck on a blank meant for another denomination.
- Double strikes: struck twice, often with a rotated or shifted image.
Tips for Searching Your Change
To increase your chances, look through every coin you receive, especially pennies and quarters. Check for unusual shapes, missing elements, or extra details. Coin roll hunting—buying rolls from banks and searching them—is a popular hobby that yields more errors than casual pocket change. Online forums and clubs can help you learn what to look for.
- Examine both sides of each coin under good lighting.
- Compare suspicious coins to a known normal example.
- Keep a magnifying glass or jeweler's loupe handy.
- Join a coin forum to get help with identification.
- Don't spend unusual coins until you've checked them.
Common mistakes
- Thinking every odd-looking coin is a valuable error—many are just damaged or worn.
- Assuming error coins are only found in old collections; they can appear in new change too.
- Not checking both sides; some errors are only visible on the reverse.
