Jusat went through my entire pile of 2600 carts to find what I need to keep for my collections and what's dups. I got 218 dups do far (there's probably more stashed somewhere I haven't found yet)
Mostly it's Atari and Sears, 1 to 3 on Atariage rarity list. I'll post a detailed list later if no one wants to buy the whole lot sight unseen. (Hozer might be interested in thos for supply of cart cases)
