RobertSI've been storing flat, but am concerned some cards on the bottom of the stack may get squashed or flattened, not to mention eventually geting stuck to their sheets. I've seen cards in screwdown holders get flattened too much.
Are you going to try to flatten the curled 1972s?
Also -- what about cig and candy cards: they seem too small to warp in a binder standing up...
