This book is for serious, experienced collectors who want the advantage for buying and selling US error coins. This book contains more than 5,000 line items with thousands of grading entries. Only coins that are certified by the major grading services are listed in this guide.

This guide has been published since 2009 and has expanded every year since with new editions. Everything in this guide is the property of the author, including all the coin photos which are from the personal collection of Stan McDonald.
This book also contains 55 error types with photos and accurate descriptions that can be used as a reference for collectors to compare potential finds. It also has an extensive glossary that has been compared to major numismatic organizations to ensure accuracy.

Collectors need to be concerned about self-published error coin guides listing coins as errors that do not exist, like the "In COD WE TRUST" coin, which does not exist. The effect is caused by a font design where the "G" in "GOD" resembles a "C," often due to a short stem and lack of a crossbar, or in some cases, grease-filled dies during minting. These are not true mint errors but rather a design choice or minor production issue, like worn dies or grease, which creates the visual illusion. Despite some eBay listings claiming high values (e.g., $50-$2,000), numismatic experts and forums, such as CoinHELPu and Collectors Universe, clarify these quarters are not rare and typically worth only face value (25 cents) in circulated condition.

If you can find a more accurate self-published book with a BSR (Best Seller Ranking) in the category of "Antique & Collectible Coins & Medals" under 75,000, I will pay you $1,000.
