The word Numismatics comes from Latin origin and means the study or collections of coins, tokens, paper money, and sometimes related objects (such as medals)1. When discussing the value of coins it is important to distinguish between the bullion value of a coin (i.e. the coin’s value based on its precious metal content) and its numismatic value. Coins with numismatic value (“numismatic coins”), are collectible coins valued for their age and rarity rather than, or in addition to their precious metal content. Numismatic coins are typically sold to and traded among collectors, who may be interested in them for their historical, cultural, or investment value. They may be purchased from wholesalers, national and local retail outlets and brokers, and certification labs.
