The Roman Mint was established as the Temple and Factory of a Roman God named Juno Moneta. The word money is derived from this god's name. These mints relied on vastnumbers of manual laborers. Since each coin had to be struck by hand, no two are identical..The making of each coin required the labor of three men: one to hold the coin blank in place with special tongs, one to hold the die over the blank, and one to strike the hammer blow that minted the coin. More than one hammer blow was often necessary to transfer the die image to the coin. Some coins feature a ghost image resulting from a die shift between two hammer blows. This is also why an image is not often centered on a coin.
