Ancient Roman and Ancient Greek coins are considered some of the earliest forms of currency in human history. These coins were made of precious metals such as gold, silver, and bronze and depicted engraved images of mythological figures, gods, and emperors. The earliest examples are dated as far back as the 6th century BC. 

In addition to their use as a means of commerce, they also collected for their artistic and historical value. Collecting coins, also known as numismatics, can be traced back to the ancient world, where wealthy individuals amassed rare and valuable coins to signify their status, wealth, and curiosity.
