Hmm... to me it looks like a drastically "aged" version of these modern fakes: Edited: Nemo has it right. Search Forvm's fake reports for more.
This is why I despise dealers that sell modern fakes. They say no harm as long as they clearly state they are selling a fake, or its a copy with the label copy...like the one above. But as OP's example shows us, all it takes is for someone down the road to take that fake example and alter it to make it look genuine, for someone else to be harmed by it. Destroy the fakes in your collection, and save someone down the road from becoming an unwitting victim of it.
Destroying 99% of all fakes will do no good unless we can convince people to stop buying rare coins from people who prey on those who do not know the difference. We would be better off having one of these fakes in every collection and having everyone know what they look like. Did the most recent seller of the coin know? The one before that? Copies are not the problem. When the copy is made to look old and authentic, the problem begins. When it is sold as real by someone who does or does not know and we insist on buying from them, the drama continues.
