With the rapid growth of our nation, there was a demand for more currency. During the 1920s, the U.S. Treasury realized that millions of dollars could be saved by replacing large-size or "blanket" bills with smaller bills. The currency most familiar to Americans and to the world today, Small-size currency has been issued since 1928 in many forms: Legal Tender notes, Silver Certificates, Gold Certificates, Federal Reserve notes, National Bank notes, and Federal Reserve Bank notes. The last "large-size" or blanket bills were printed in 1929.
