Picayune
A picayune was a Spanish coin, worth half a real or one sixteenth of a dollar. Its name derives from the French "picaillon", which is itself from the Provençal "picaioun", the name of an unrelated small copper coin from Savoy. By extension, picayune can mean "trivial" or "of little value". Aside from being used in Spanish territories, the picayune and other Spanish currency was used throughout the colonial United States. Spanish dollars were made legal tender in the U.S. by an act on February 9, 1793. They remained so until demonetization on February 21, 1857. The coin's name  first appeared in Florida and Louisiana, where its value was nominally one sixteenth of a dollar, i.e. cents, and whose name was sometimes used in place of the U.S. nickel. A newspaper published in New Orleans since the 1830s, the "Times-Picayune" (originally "The Picayune"), was named after the coin. A city in southern Mississippi has the name Picayune.
