US Coinage Error Reference
This reference has been created to help collectors learn what errors are, how to spot them, and showcase our collection for examples. The various categories of errors have been organized into three main types; Planchet Preparation, Hub And Die, and Strike Errors. We have tried to include all known varieties and sub-types along with specific ways to identify the differences.
To better understand numismatic errors, it helps if one knows the basics of the coin minting process. There are certain terms that are used that may need to be explained to the novice collector. To that end, we’ve created a page that will explain the process and help define the terms used in our hobby.
