I don't know much about old Russian coins but I found this one interesting. It was very cheap. I know authentic ones are very expensive, but the seller knew nothing of coins, so I took the risk. 1755 Elizabeth Rouble. It is 39mm in diameter, should be 41mm. It weighs 23.94 grams, which is about 2 grams too light. The M on the reverse under the eagle's leg appears to be in the wrong font as well. However, I found the die clash on the obverse to be interesting. And then there is the matter of the edge lettering... Lettering isn't even close to what an authentic example should have. Almost looks like numbering for a limited production. Like I said, I don't know much about Russian coins so if anyone knows more than me, you are more than welcome to chime in. I also looked into the possibility of a novodel but that doesn't seem to fit this case either, so most likely just a fake, or maybe a contemporary counterfeit.
Is it magnetic and weigh it that's my suggestion but that's not always true either because I found three Henning nickels and none of them weighed over 5 G and they're supposed to weigh like 5.4 G
Dunno man, looks pretty legit to me. It doesn't have any of the typical "modern" counterfeit signatures. Z
That's my other question, what were the standards for uniformity of coins being made during the 1750's in Imperial Russia?
Unfortunately fake. The coin is a bit too round and edge is completely off - the text should not be incused and totally different text should be there (MOCKOBCKOTO MOHETHOTO ABOPA).
Unfortunately modern. The edge is a dead giveaway. The clash is definitely interesting. Cool item, glad you got it on the cheap
