I didn't take the time to read through this thread but for me during the 70's/80's, I used either 9 pocket binder pages or my personal favorite for rounding corners over time, The Ace Case. There was nothing quite like it when it came out. I put all my Willie, Mickey, and Hank's in these... Just enough room to slide around for all 4 corners, but they looked great in those Ace Cases! For every 6 months you kept a card in an Ace Case, you would gain a ding or two, thus hurting condition.
