I have an early 1920's strip card of The Babe that I badly creased right across the center, almost made two cards out of one when I stupidly tried to move it out of a pocket in a 15-pocket sheet and into another one to get a few Ruth cards together, and since its The Babe I wont get rid of it and its too expensive to replace, but I do get aggravated every time I look at it.
I no longer move cards around in my sheets.
