The first 10 or so shuffles of a new deck of cards may be relatively common, but after you put a deck of cards away you are not going to reorder it. Most aged decks are therefore going to be completely unique in their ordering.
The only people who use new decks frequently are casinos, and they have very good shuffling machines. It is likely that every deck dealt in a casino is unique.
I don't know, I end up reordering cards often enough when trying to figure out which card is missing, or because I just won a game of solitaire or what not.
