I'd love to have any coin from the Christopher Salmon Collection real or not. A great provenance to have, regardless what the TPGs and experts agree on or don't agree on. It's a neat coin and it wasn't stupid money, while still expensive if it turns out not to be I think you did okay.
Composition of metal would not be definitive either as any counterfeiter that is worth his weight would be using an old coin from the same era that is worth a lot less to melt down for the metal to make this one, that way it would pass all the metallurgical tests.
