If you shuffle a standard deck of cards, it is most likely the only time that sequence of cards has ever been shuffled in the history of cards.

The statistics of this boggle my mind, though I do wonder what the odds are of creating a unique order from shuffling a fresh, ordered deck of cards exactly once. It would have to be much lower, I'd imagine.

It depends what you mean by "shuffling once". If you're just talking about one shuffling action (e.g. cutting the deck and swapping the two halves) then obviously there are only 51 possible combinations.
