Roman Silver Coins
Unlike most modern coins, Roman coins had significant intrinsic value. However, while the gold and silver issues contained precious metals, the value of a coin was slightly higher than its precious metal content, so they were not, strictly speaking, bullion. Also, over the course of time the purity and weight of the silver coins were reduced.The coinage system that existed in Egypt until the time of Diocletian's monetary reform was a closed system based upon the heavily debased tetradrachm. Although the value of these tetradrachmas can be reckoned as being equivalent in value to the denarius, their precious metal content was always much lower. Clearly, not all coins that circulated contained precious metals, as the value of these coins was too great to be convenient for everyday purchases.
