Just had a chance to go through a collection of mostly bronze/copper/modern age books. A guy I work with knows I collect comics and he told me when he was a teenager he bought plenty of them. He told me he had about 3,200 comics, all bagged and boarded, that I could come look at after work.
Obviously I sped over there the second I got off.
I got there, and he was definitely right - there was over 3,000 individual comics all bagged and boarded. Everything was basically VF or NM, and I'd say the majority of them will grade around a 9.6. Most of the stuff I picked up is just reading material, but there are a few keepers.
After flipping through every book he had, I walked away with the following for a mere $40 because he basically just wanted to clear everything out (and didn't really care about value, as he hadn't kept up with it in years).
Green Lantern (1990) #1-30
Amazing Spider-Man #313-400 (I have a lot of these, but I needed a few for my collection and figured I'd could sell the extras off in lots)
Aquaman (1985) #1-5
Web of Spider-Man (1985) #34-109
Spectacular Spider-Man (1976) #162-245
Uncanny X-Men: #200-366
The New Mutants: 87, 98
The Uncanny 266 and New Mutants 98 look brand new, those will be the 2 big keepers that I found, and will definitely go to CGC. I'm pretty sure both will fetch a 9.8 as he bought them off the shelf and bagged and boarded them immediately. I was actually surprised they looked so good.
So, I think I got enough bulk issues to warrant my spending of $40, not to mention the 2 going to CGC.
