Sakata, I know zilch about Russian coins but other things about the listing tell me to run, don't walk.
It has "the look" lol. Photo or scan doesn't really change that. But aside from that some details are wrong. This coin in this grade would be over $100k and this variety with signature below the bust is extremely rare.
Oy! It sure does look extremely "fakey"! Mind you, I don't know the type, but this one throws up all kinds of instinctive red flags with me. It just looks ... "off".
