Error Coins

  • What is an error coin?
    An error coin is a coin that left the mint with a mistake, such as a wrong planchet, off-center strike, or doubled die. These errors happen during production and are not intentional.
  • How can I tell if a coin is an error?
    Look for unusual features like off-center strikes, doubled text, or wrong metal color. Compare with known examples and use a magnifying glass to check details.
  • Why are error coins valuable?
    Error coins are valuable because they are rare and highly sought after by collectors. The more dramatic and scarce the error, the higher the price.
  • What are the most common types of coin errors?
    Common errors include off-center strikes, broadstrikes, clipped planchets, doubled dies, and wrong planchet errors. Each type has distinct characteristics.
  • Can I find error coins in pocket change?
    Yes, error coins do occasionally show up in pocket change, but they are rare. Most circulating coins are perfectly normal, so finding one takes patience and luck.
  • Should I clean an error coin?
    No, you should almost never clean an error coin. Cleaning removes original surface and patina, drastically reducing its value to collectors.
