If you check the Bureau of Engraving & Printing website (www.moneyfactory.gov) check out the store, and you will see that the are selling 4-subject, 8-subject and 16-subject sheets starting from $480 to $1,776 depending on the size sheet you get. (I really wonder if the $1,776 pricing for the largest sheet has anything to do in the Centennial, or if its just an odd coincidence)
I wonder how much uncut $500 bill sheets will cost if they reissue the $500 bill.
