The year 1892 saw the designs of Charles E. Barber, also designer of the Morgan dollar, adorn the dime, quarter and half dollar. His Liberty Head nickel had debuted in 1883, and thus from the years 1892 to 1904, his designs were featured on every denomination from 5 cents up to one dollar. The Barber design would last on dimes and quarters up to 1916, on half dollars up to 1915, and on the nickel up to the extremely rare and famous 1913 Liberty Head nickels.
Federal Reserve Notes were issued for the first time in 1917. Originally, these were backed by gold, and a note could be, at least in theory, exchanged for gold coin at a bank until 1933 when gold was confiscated from the general public. Silver certificates were exchangeable for silver coin up to the year 1964.
The design of the American One dollar bill has stayed almost the same since 1935, and the other denominations had a similar appearance until their redesign in the late 1990s.
The Gold Eagle was re-designed in 1907 as the Indian Head eagle and the $2.50 and $5 pieces followed in 1908. The Liberty Head Double Eagle was replaced with the St. Gaudens Double Eagle in 1907. The wheat penny was introduced in 1909 and the Buffalo nickel and Mercury dime were both introduced in the 1910s (1913 and 1916, respectively).
The Peace Dollar was minted from 1921 to 1933. After 1933, no more gold coins or silver dollars would be minted by the US Mint until the bullion and commemorative series that began in the 1980s and continue to the present day.
