Cash a car riddle


A man is going to an Antique Car auction. All purchases must be paid for in cash. He goes to the bank and draws out $25,000.

Since the man does not want to be seen carrying that much money, he places it in 15 envelopes numbered 1 through 15, in such a way that he can pay any amount up to $25,000 without having to open any envelope. Each envelope contains the least number of bills possible of any available US currency (for example, no two tens instead of a twenty).

At the auction, he makes a successful bid of $8322 for a car. He hands the auctioneer envelopes 2, 8, and 14. After opening the envelopes, the auctioneer finds exactly the right amount.

The question: How many ones did the auctioneer find in the envelopes?

    What I am missing in the question is what bills are available in the US currency.
    Of course I can look it up but it should be mentioned in the question.
    Obviously the bills are not the same as for the Euro currency, because the Euro doesn’t have any 1 Euro bills only coins.
