Hello,
Here are two coins. The dies are same. The firt coins is with
CONOB mint mark. The second coin with
COMOB. There are cases. The die was reheated and then cold worked. The metal could be pushed back and you should see depressions. Sorry if my traduction is not correct, im
french.
COMOB then
CONOB or
CONOB then
COMOB.
COMOB to
CONOB look the more simple but the
obverse style match with
Constantinople.
The problem is that the photo
quality dont permit to see remains of this
work on both coins. Do you have a better photo of this coin?
