Metal: Silver (AR), though the silver content in tetradrachms from this period is notably low. These coins, struck during the reign of Trebonianus Gallus (AD 251–253), often contain a significant amount of copper, giving them a more greyish or dull appearance. The estimated silver purity is around 30–40%, but this can vary.
