Falsa de época
A period or contemporary counterfeit, made long ago to deceive merchants, not collectors during the period when the copied coin circulated. It is usually base metal, struck from crude dies or cast, some then plated. Often, these coins circulated with legal coins and were accepted if the weight and metal matched legal coins. Some historic counterfeits are collected, such as American colonial coin types.
