After seeing this seller selling too many fake Russian coins, I have gone completely sick and tired.
One excellent example is this link:

A genuine or rather novodel 1836 10 ruble with the medallic reverse is exceeding scarce and the price tag is way too cheap. If I am not mistaken, the last time I saw such medal on auction was at least over 20grand, which makes this at least 10 times too cheap! Needless to say, the font of the signature, Gube is too wrong.
When you check his negative feedbacks, it seems that the nature of how he words his auction listings - he actually does not guarantee that his coins are genuine - pretty pointless isn't it?
Quite often he auctions off ultra scarce rare pattern coins but most of them can only be found in expensive auctions or most likely in museums.
