Sorry, but your coin is a modern cast.
Here are the scans of the same coin. Sold on
Ebay in June 2004 as a reproduction.
Heavy 19th Century(?) cast copy of a
Paduan(?)
Medallion, weighing 51.4 grams (over two ounces), and measuring 35 mm across and 4 mm thick. M COMMODVS
ANTONINVS AVG PIVS BRIT, laureate, draped and
cuirassed bust of
Commodus facing right, in high relief. /
P M TR P …., with
VOTA PVBLICA in the
exergue.
Commodus stands, facing left, sacrificing over a tripod-altar, while a
victimarius sacrifices a
bull, with a temple in the background (a
rare sestertius with similar scene was struck in 191 A.D., near the end of Commodus' reign).
