These notes are reprints of actual notes or "funny money" and are not legal tender.
USA Over-sized banknotes
These are over-sized reprints of banknotes that are no longer printed. I bought these as one set when I visited The Bureau of Engraving and Printing in Fort Worth, Texas. Other than the 100,000 dollar note, all of these were in circulation of some sort at some point. The 100,000 dollar note was never released into circulation as its primary purpose was to transfer large amounts of money from bank to bank.
These notes are not legal tender, however, they can be redeemed for their face value for a certain period of time.
