Roman coins were a form of currency used in Ancient Rome. The two most common coins were the DENARIUS and the sesterce. The DENARIUS was a silver coin that was first minted in 211 BC and was the most common coin in circulation until the 3rd century AD. The sesterce was a bronze coin that was introduced in the 1st century BC and was the largest denomination of Roman coinage. Both coins were widely used throughout the Roman Empire and were accepted as payment for goods and services.
