IBM had duplicating punches that could handle really
mangled cards.
For example, the punch cards used by tube dealers back in the 1960s
(used for reordering) were typically folded in three inside a sleeve
of tubes.
I remember back in the early 80's, Con Edison used to send a punch card
with their bills to be returned with a check and the inscription "do not
fold, staple or mutilate." :-)
