Joseph W. Barr served as U.S. Secretary of the Treasury from December 21, 1968, to January 20, 1969 - less than 1 month - the shortest term of any Treasury Secretary. United States paper money always depicts the "signature" of the Treasury Secretary and because of Barr's extremely short tenure, only 458.88 million series 1963-B one dollar bills were printed bearing his signature - and no other denominations were printed with his signature at all. With paper money typically wearing out after just 21 months of general use, it is thought that very few - if any - "Barr Bills" still exist in circulation.
