The United States has produced several coins and banknotes of its dollar which no longer circulate or have been disused. Many of these were removed for specific reasons such as inflation reducing their value, a lack of demand, or being too similar to another denomination.

Treasury notes

The U.S. Dollar has numerous discontinued denominations, particularly high denomination bills, issued before and in 1934 in six denominations ranging from US$500 to US$100000. Although still legal tender, most are in the hands of collectors and museums. The reverse designs featured abstract scroll-work with ornate denomination identifiers. With the exception of the US$100000 bill, these bills ceased production in the 1940s, and were recalled in 1969. Of these, the US$100000 was printed only as a Series 1934 gold certificate and was only used for internal government transactions. The United States also issued fractional currency for a brief time in the 1860s and 1870s, in several denominations each less than a dollar.

Coinage

There have been numerous coins throughout the United States dollar's history that no longer circulate. Some, like the half-cent coin were removed due to inflation reducing their value while others such as the two-cent piece were removed due to a lack of demand. Note that this table shows the latest status before the coin denomination was rendered obsolete.
