I bought them relatively cheap due to them being jewellery pieces, which I didn't mind or else I have to be forking thousands of dollars which I am not going to do any day soon. However today when I decided to pair them up against Uzdenikov's catalogue, I can't really find any pieces similar to what I got, which means chances are too high that both of them are countefeits

Here are two rubles, one of which seems to be of the mintmaster OK and the other, K.







What are your opinions?

Note - the second piece is gilted if you were wondering about the wierd gold color.

In my amateur opinion the second coin is a fake.

These coins are worn, ex-jewellery. The second has graffitti and has been gilded, so both coins would bring substantial discounts below current market if sold, but that is because they have had a hard life.

It is foolish to declare a coin genuine based solely on a picture (although that can sometimes legitimately be done with an obvious fake) but I see nothing in these pictures that causes me to doubt the authenticity of these coins.

That's probably "KO", not "K".

OK and KO are the signatures of Otfried Koenig, a German medallist and coin die engraver who worked at the Moscow mint 1718-1724. Koenig was one of the many foreign engravers Peter I (and his successors) hired to work in the Russian mints.
