I know I found a ton of stuff I forgot I had or couldn't find for the last few years. I have now burnt around 100K cards and have another 20K ready to burn.
I have almost started to make a dent in the room full of cards I have.
I am pulling error cards from the junk era and everything else from that era is going including the rookies and super star cards. The only thing I burned that I wished I hadn't was 2 1990 Donruss Aqueous cards I accidentally threw in the to be burned box. I realized it before I burned them but was not going to go back through several thousand 90 Donruss to find a Jeff Treadway and another common Aqueous card.
