The seller guarantees that this is an original coin from an old collection. It appears to be Diakov 3 (Coins of Peter I, page 127) but there is only one published die pair known for this listing and the above coin does not match either the obverse or reverse die. For those who have a good illustration of Diakov 3 the reverse crown seems to be one of the main points of difference.

The Diakov illustration is from plate XXX, 4 of the Grand Duke's corpus volume on the coins of 1682–1710.

What makes it very suspicious to me (I don't have access to Diakov) is that he is also selling a rare 18th century gold ducat, and starting both auctions at 1 Euro. Some well-known and reputable sellers can afford to do that, but this guy has only a feedback total of 26! I always stay away from auctions like this.

Looks like a product of the Guangzhou coin factory #14 to me.
