Ok, so you all give up..
.
its presented as a 1765 5 kopeck, with no mintmark. Not a common coin.
BUT
the eagle is of the later years type, which wasnt used until the 1780's
If you look at the where the mintmark is supposed to be, it looks messed with.
the last 2 digits of the date are obviously altered. Im just wondering what was the original date.
could have been a 1785.
worthless junk. but what really irks me is the seller is a supposed numismatist, so either they didnt catch it

or dont care that they are selling this junk
