What do you think the percentages are? Seeing the last couple of Mantle's and Dimaggio's on Ebay, It got me thinking how many of the bad signature are knowingly being sold by the seller? How many were gifts or items they bought and really don't know the authenticity? Every time we see these obviously fake items being sold, do you assume the seller knows? Here is my guess: 90% are being sold with the seller knowing the item is bad. Your opinion?
