Ecuadorian sucre coinage

Ecuadorian sucre coinage encompasses the metallic currency of Ecuador issued between 1884 and 2000, when the sucre was replaced by the United States dollar. Named after the political leader Antonio José de Sucre, the currency was established in March 1884 on a silver standard and was subdivided into 10 decimos and 100 centavos. The initial series included cupronickel half-centavo pieces alongside silver half-decimos, one- and two-decimo coins, and half-sucre and one-sucre denominations. Copper replaced cupronickel for the half centavo in 1890, and gold ten-sucre pieces were issued in 1899 and 1900. Base-metal fractional coins in cupro-nickel followed between 1909 and 1918, while the production of silver coinage was suspended in 1916.

In 1928, a substantial currency reform introduced a new series dubbed "Ayoras" after President Isidro Ayora. Under this reform, the one-sucre coin was reduced from twenty-five grams of ninety per cent silver to five grams of seventy-two per cent silver. Further base-metal issues were added in subsequent decades, including nickel and brass pieces. The final silver coins were two- and five-sucre pieces struck in 1944, after which cupro-nickel predominated before nickel-clad steel replaced previous alloys between 1959 and 1970.

Severe inflation during the late twentieth century prompted the issue of higher denominations and new compositions. Nickel-clad steel coins of ten, twenty, and fifty sucres appeared in 1988, followed between 1995 and 1997 by bimetallic pieces of one hundred, five hundred, and one thousand sucres. Sucre coinage ceased regular circulation following the economic crisis of 1998 to 1999, with the United States dollar becoming legal tender in March 2000. Over the course of the currency's history, several issues of sucre coinage were struck abroad.

The series is distinguished by its shifting metal compositions, moving from early silver, gold, and cupronickel strikes to mid-century nickel-clad steel and late twentieth-century bimetallic high denominations.
