So I have 10,700+ baseball, basketball and football cards taking up room. Some valuable I am sure. My question to you ATOT is this: What is the best way to go about selling these things? Sell them all in one big lot on ebay? Go to card shops and try to sell them one at a time? Anyone ever dont this before? I am worried I am going to sell the lot then later find out I had a $500 single card in there. I put them up on ebay in one giant lot but I am now having second thoughts. Did I take the best route or should I cancel the auction and sell one at a time?
