Error coins are rare and unique coins that have mistakes from the minting process. These mistakes can make the coins highly valuable to collectors. Among U.S. coins, quarters are especially popular for error hunters because they are widely used and have an interesting history.
This article highlights the top 10 most valuable quarter error coins that you might still find in circulation or available for collectors.
What Are Error Coins?
Error coins happen when something goes wrong during the minting process. These mistakes can be small, like tiny misprints, or large, making the coin look completely different from its intended design. Some common types of errors include:
- Off-Center Strikes – The design is not properly centered.
- Double Dies – Parts of the design appear twice.
- Clipped Planchets – The coin has a missing piece due to improper cutting.
- Overdates – A new date is printed over an old one.
The value of an error coin depends on factors like its rarity, the type of mistake, and its condition. Even a coin found in regular circulation can be worth a lot if it has a rare error.
