The first auction I ever went to was 3 years ago at a Monday morning auction. I was 36 I think the next youngest person was 75. So I imagine they had no clue what Magic cards are.
They had a bunch of shelf lots. 2 of them were completely packed with Magic cards. I can't remember the total # but there were well over 50,000 cards. I won both shelves for $30 each. I knew nothing about them so on the way home i took them to a card shop near me and the guy offered me $1,000 for the lot. I declined and over the next month I took the good cards out and Sold them individually on Ebay. What was left I sold in groups. I made around $4,000 on that lot. All at my first auction! I thought wow this is easy....boy was I wrong. 100 auctions later and I never came close to scoring like that again.
