Here you will find cards I have once owned but no longer do. This can be because I come across a small lot of cards and there's no set and I have none of them. Found a person who needs that one card for a set so I'll let it go :)
Personal story of this just recently. Went to an antique store, bought a box of cards for $5. They were all bent up but 1960-1980's. Well I found 4 1978 Superman the movie cards! condition: excellent. A graded card of 10 I saw selling for $75. Well I knew I wasn't going to get that but I found another card collection site and I came across a person who had the entire 77 card set except one of the cards I have :) Once I get pics of the card, I'll work a deal with him and complete his set! Afterall that's what I'm doing, making and completeing sets.
