Buying collectibles at stores and putting them on Auction Sites and if they don't sell return them for a refund. Recyling - we are sure the mulitude of forged autographs purchased will be recyled either through auctions or at shows. With what we are seeing it has been going on or there is new group in action. Sprinkling - Placing bad material in with good material. More common than you would think.
Ignorance is no excuse.
Mis-representation of items. Great example we noticed listed on Auction by a dealer. To make things worse it was another item signed by Joe's sister, not even a real autograph. On auction listings using memorabilia companies names in the item description so the search engines pick up their item. If someone uses these deceptive practices please do not support them.
