Welcome to Bayworld,where the only people who are right is E bay itself and the buyer. The seller has NO rights. Take the return and move on . There is nothing else you can do. Last year we sold 8 1953 Canada Silver Dollars from an ORIGINAL bank roll to a bidiot who returned them saying the reason was he could not make money on them trying to resell them!! Glad he returned them as it really. worked out for us after we then sent them for certification. Six of them ended up as MS 64!
SsuperDdave may well be right.The time is RIGHT for something else to replace what Jokebay has become.
