The U.S Bureau of Engraving and Printing is the only agency authorized to develop and produce United States currency notes. The BEP prints billions of dollars each year for delivery to the Federal Reserve System.
When currency becomes badly soiled, dirty, defaced, disintegrated, limp, torn, or worn, they may be exchanged for new notes, through your local bank. These damaged, no longer useful notes are removed from circulation, and returned to BEP who will shred the bills. Believe it or not, these shredded bits of US currency can be purchased directly from BEP . . .
I, however, found this bag of shredded money at a local garage sale recently.
***A mannequin head wearing rim-less eye glasses, is covered in bits of shredded currency, and sits atop several CDs and a 1945 Standard American Encyclopedia Volume 1 A - Art.
A small glass bottle is also mounted on the book, filled to overflowing with money. Two vintage brass drawer pulls anchor the piece. Note the feet under the book . . . are vintage brass toilet seat hinges.
