Photos of all errors with complete descriptions validated by PCGS and NGC terminology provide collectors with information to identify the type of error. All types of errors from striking, planchet, and dies that collectors can locate from old collections, bank rolled 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. Major Error Categories Die Errors Die errors are created from broken dies, cracked collars, hub errors, misaligned dies, doubled dies, and repunched mintmarks.
