I sent a message to a seller on eBay who seems to be new to slot cards and he was listing a bunch of really common slot cards with starting prices of $6.99. I suggested he might want to download a copy of the Slot Card Guide if he needed help with prices/values. I was interested in a Four Queens bus card that had a bus group# I need but they normally only go for $1 to $3 each. I never got any response from the seller but I just noticed he changed the starting price of the 4Queens card to $50,000
