The coins shown in the jewelry pieces below are authentic, once circulated currency, and have been inspected and authenticated by numismatics specializing in Greek and Roman currency.

Of course, there are some coins that are very rare but the majority of the ones you see here are found regularly and do not have any regulation set on their trade due to the sheer number that are found. For example, Alexander the Great minted some 13 million silver Tetradrachams over just an 18 year period 300 years prior to the Roman Empire. He used up to 20 talents (half a ton of silver) per day paying and rationing his army.
