Book Description
The 2020 guide contains new photographs for describing the classification of error coins. Collectors and organizations dedicated to collecting coins' regard mint striking errors as those created by the mint stamping process. Mint striking errors include: double struck (not to be confused with doubled dies), multiple struck, indents, saddle struck, off-center, brockage, broad struck, and die caps. Many coins in circulation appear doubled, but the appearance of doubling is machine doubling and not die errors. A planchet error deemed as a transitional mistake results in minting coins on planchets intended for a previous mintage. For example, in 1943, the mint changed the planchet to steel.Variations are not mint errors in the technical sense. Creating hubs and dies that are not precisely the same result in dates compared as large to small, "wide" to thin. In early U.S. coinage, there are dates of coins that have multiple numbers of variations in date size, appearance, and so forth.
