100 Dollars Federal Reserve Note, Large 100, Branch ID in Numbers

The 1928 series marked the Federal Reserve's shift to the small-size format — a dramatic reduction from the "horse blanket" notes that had dominated American wallets since the Civil War era. The changeover was driven by cost and mechanical efficiency, not aesthetic preference, and the BEP retooled significant press capacity to accommodate it.

This particular variety is distinguished by the branch identification appearing as numerals rather than letters — a cataloguing distinction that matters more to specialists than it did to anyone spending the note. The Federal Reserve Bank district number appears twice on the face, a design convention that survived into much later series.

Series 1928 notes were signed by Secretary of the Treasury Andrew W. Mellon and Treasurer of the United States H.T. Tanner.
