The Series of 1928 was the first issue of small-size currency printed and released by the U.S. government. These notes, first released to the public on July 10, 1929, were the first standardized notes in terms of design and characteristics, featuring similar portraits and other facets.[1] These notes were also the first to measure 6.14" by 2.61", smaller than the large-sized predecessors of Series 1923 and earlier that measured 7.375" by 3.125".[2]
Certain one-dollar notes in this series were called Funnybacks.
