Here's a clipping from the SCWC ....
All three look different. And with it known the the 1799 was widely counterfeited, who's to say that the one that the one on the Russian site for sale isn't the counterfeit ...
I have several Russian coins from that era, and setting them side by side, there are differences .. Especially those from a type having several years, with differences between mints and mint masters ...
What other than comparison, makes the one listed on Numista the fake .. ?? I would like to know for my own interest.
Kind regards,
Fred....
