Covering all recognized error coin types, this guide features photographs from the author's collection, sold coins, coin shows, and live auctions. Its primary goal is to provide collectors with accurate error coin definitions and images, endorsed by ANA, NGC, ANACS, and PCGS, alongside reliable values for confident buying and selling.
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.
