I would like your help in identifying and evaluating this ancient coin that I own. It is a Byzantine coin, and I have attached clear photos of both sides.
Description:
On one side, there is an image of Christ with a cross and inscriptions in Greek.
On the other side, there is a large “M†symbol with surrounding inscriptions and letters.
I would appreciate any information regarding the exact type, date, emperor, historical context, and estimated market value.
Thank you in advance!
