Worn and rough surfaces, holed at 12h. An exceedingly rare bronze medallion struck for Marcus Aurelius as Caesar, previously known from just a single specimen in the Berlin Museum, acquired in 1860 and cited by Gnecchi, Strack, and Mittag. (Strack cited an additional example from Bologna, but Mittag was unable to confirm the existence of such a specimen.)
This coin is a double die match to the Berlin coin, the only known specimen in private hands, and apparently the first to come to light in more than 160 years.
