Some honest wear and a few spots of corrosion, but a handsome and impressive coin nonetheless. Very interesting reverse. I'm not familiar with whatever the narrative is there. Looks like Asclepius and the bull are having some deep conversation.
Even with the wear and the corrosion spots, this particular specimen is far better than what is typically available. For instance, consider the specimen at the Staatliche Museen zu Berlin below. As for the narrative of the reverse, there are two competing theories:
1) Asclepius is healing the Bull OR
2) According to the cult of Asclepius, the first leg of a bull is sacrificed at the altar to Asclepius and hence this could depict that sacrifice.
