I used to mock people who bag their comics with backing boards super tight until a dollar bin pull had cover roll so bad it looked curved. Slipping a clean board behind and using a heavy book for 48 hours fixed it flat enough to grade decent. Anyone else fix cover roll with household weights or am I just cheap?
Wait, a dollar bin pull had cover roll so bad it looked like a taco shell? That part is wild to me. I have seen some rough books in bins before, but a curve that bad usually means somebody stored it under a stack of encyclopedias for a decade. The heavy book trick working in 48 hours is kind of amazing, not going to lie. My own fix was way less classy, I just shoved a few hardcovers on top and hoped for the best. Your mileage may vary depending on how bad the roll is, but that seems like a solid save for a cheap book.
