As I sit and write this, I am surrounded by 50 5000 count boxes. And I have smaller boxes that could probably fill another 7-8. I also have a reasonably decent high quality collection, too.
I'd love to figure out how to get rid of almost all of the 5000 counts without having to throw them away or basically donate them. I know if I spent the time to dig through all of them that you would find cards worth much more than $5. Heck, the other day I found a Trout Topps Update RC sitting loose in one of them.
Still waiting on an Odell/Landry dual auto from Topps
I don't sell anything under $10. It's not worth my time.
