Nevertheless, I have read that there are novodels of such rubles and at one stage Uzedenikov in his earlier books noted that there is no way that you can tell the differences. Can one tell the differences?
There are enough differences in the obverse design that, given good pictures of genuine coins, it is possible to quickly see that this is one of the more common fakes. To me (entirely subjective criteria, of course) the genuine obverse shows a facial expression which is much more gentle or benign, looking slightly upwards, whereas the fake looks much angrier and is staring almost straight ahead.
As to novodels, etc. -- yes, there were some "official" restrikes made by the Soviet Philatelic Society in 1927 as well as some earlier novodels after most of the original coinage was melted down (there are only about 150 coins out of the original 30,000 left, according to Kazakov). The Kazakov catalog mentions three varieties, but only in these combinations:
1. Both obverse and reverse normal: = normal striking;
2. Obverse proof, reverse not: = novodel;
3. Obverse normal, reverse proof: = 1927 restrike.
This is all I know about the Gangut roubles, and I never bought one myself. I'll now let others take over where my very limited knowledge leaves off!
