As illustrations of the life and religion of the Romans under the Empire, as well as of the history of the times, no numismatic monuments which have come down to us can compete with the large bronze medallions. They are to be distinguished from the current large brass coins by the absence of the letters s.c. (_senatus consulto_), as well as usually by their larger size, higher relief, and finer work. As, however, the prices fetched by good medallions are, as a rule, very high, they are practically out of the reach of the collector of moderate means. § HOW TO DISTINGUISH TRUE FROM FALSE COINS.
