In recent Dimitri Markov auctions, he auctioned some unique overstriked coins, which is quite interesting.
If you are talking about lot #1119, then you are up for a big surprise -- the description in the catalog was BS. I was there and I saw the coin. It probably had a damaged edge, and then some moron made a new edge by hand. It is my opinion of course, and it is not beyond contestation.

But if you look at the picture in the catalog, you will see rim dings going around the whole circumference of the coin. Those are the marks of hand-punching.
There were a couple of super rare coins there, like 1707 ruble small head, 1714/3 ruble, etc. But they were far from superb. The above two coins, for instance, were artificially toned. Lot 1087 was superb, however. Too rich for my blood though. The rarest one was 5 kop 1771 lot #1335. That was my favorite. Too bad it did not become mine.
