I'm thinking to buy this rouble on ebay, but have some concerns about the authenticity, even with seller guaranteeing that it’s authentic. What do you think?

I think it is genuine but unfortunately if you look at the bottom of the coin, it seems like it was intentionally worn off, which painfully removes a fair amount of it's value.

Thanks for the fast reply, the price doesn't seem to be that bad for this one, I can't afford it in VF

Funny timing on your question. I was going to ask the forum about this different 1762 rouble that was just listed today. The seller has been around for awhile and seems to have good quality things, but I had to look at this one closely. My first impression is that it has the cast look to it. Maybe I am being too critical?

This coin is genuine. However, it has been harshly cleaned with chemical agents. That brings the value of it to a very low level. Also, it looks like attempts were made to add artifical toning to it (most likely , to cover the cleaning). I'd stay away from this expensive problem coin.
