Hello!
Recently I've gained an interest towards coins from the Russian Empire. It's become pretty clear that Russian coins are often counterfeited and that obviously makes me quite nervous as I do most of my coin purchases online. I would be interested in finding resources regarding coins of the Russian Empire to educate myself better and possibly learning to identify counterfeit coins more easily. I found this site: http://numistika.com/counterfeit.html but it doesn't have pictures of coins from 1742 and up (at least anywhere I looked).
Any tips are highly appreciated! I would prefer online resources but books are not out of the question, I would just have to be extremely lucky to be able to find those books from a library in my country.
