I'm certainly not an expert or even knowledgeable on these, but sure looks fake to me ....11 foot pole marks all over it.
I do not claim to be an expert on these but the mushy details would cause me to think twice before purchasing.
I think the OP coin is fake, without a doubt - wrong style, bad style. If Empress Anna Ivanovna saw something like that coin, the maker would certainly have a one-way ticket to Siberia. Here's an authentic Anna ruble for reference: Russia, Anna Ivanovna, ruble, 1733, Kadashevsky Mint, Moscow. KM# 192.2 25.7 grams
Yes, it is fake. Found copies of it for sale as a reproduction and a very poor one at that. The style is cartoonist along with other problems. I didn't really doubt it but I always like to get another opinion, even when I am certain. There are certainly far more convincing fakes of this coin type, but this is not one of them. Thanks.
