2023 US Error Coin Guide: Unsurpassed and Comprehensive

Welcome to the latest version of the US Error Coin Guide presenting over 3,500 listings for all types of errors with more than 20,000 listings. Our number one selling guide for collectors for fun and profit.

Error coin collecting is a growing hobby and family fun. Every year this guide is updated with new and exciting finds. No other guide presents as much information about error collecting. Photos of all errors with complete descriptions validated by PCGS and NGC terminology provide collectors with information to identify the type of error. A chapter is dedicated to presenting all known Lincoln cent DDO/DDR and RPM errors since 1909 with photos.

All types of errors from striking, planchet, and dies that collectors can locate from old collections, bankrolled coins, and circulation. Many error coins circulate without detection since most are not well known.

Some errors are difficult to determine, but some great tools are available to make error detecting easier, especially for RPM errors, some of which are easy to overlook. There are eight doubled die classifications for explaining the types of doubled dies created by die creation.
