Medallion Public Deposited
A name generally given to the very large pieces which occur in the Roman series, and which were struck by Imperial authority in gold, silver, and bronze. It is not definitely settled whether they were used as actual currency or intended as commemoration pieces. See Stevenson, A Dictionary of Roman Coins. 1889. (s.v.).
