- Unlike gold and silver issues, Roman Imperial bronze coins contained less than the full nominal value in metal. Their value was supported by the decree of the Senate "Senatus Consulto" or SC. Almost all bronze coins issued before the late third century AD bore the letters SC on the reverse...As you can see on that one, there is a S and there was probably a C also..most probably worn off... My 2 cents!Thanks for the help everyone! Any idea what it's worth?
