Ah, the fun that results when someone without a specialized background gets involved in something where nearly everyone else does have that background...
I've seen a lot of similar situations with haunted house items - there's a lot of stuff that looks good to the uninformed but turns out to be total crap, and there's a lot of people who go through fairly reputable sellers' assistants and the like to try to get more than the stuff is worth. The assistant that posts the auction gets the fallout if there is any, and if it sells then the seller gets the money.
I guess all you have to do is add recasting to it somewhere and we can hit almost every questionable behavior short of outright theft.
