Wash trading is the manipulation of a regulated marketplace and banned in 1936 for the US stock exchange as cited in an NPR story. It was also recently reported by Forbs that "More Than Half Of All Bitcoin Trades Are Fake." This report got me thinking about cards I've been keeping a log of regarding recent eBay sales. The cards are tracked by their serial numbers and seller ID in order to keep an accurate record. When I'd ask the seller about the relisted card, I'd get the classic refrain that it was a "non-paying" bidder... up to 3 times?! It made me think that the sales were not legitimate in an effort to manipulate the market place.
Do you believe wash "like" trading is a significant issue in sports cards markets?
