What conder said. You all keep forgetting that
ebay is completely and totally biased towards the purchaser and sellers can go rot. It takes NO evidence of wrong doing on a sellers part for a buyer to initiate a case and make all kinds of claims that wreck a sellers rating. And the seller can do nothing to a buyer. And in an obvious case like this, there is NO risk on the buyers part. That coin shows up and isn't real, that buyer will have their money back so fast your head would swim.
