You have one of the more historic and easily recognizable Civil War tokens. Dix would be John Adams Dix, the namesake of the army base Fort Dix in New Jersey. In January of 1861, Dix was appointed as Secretary of the Treasury by President James Buchanan(Lincoln was not inaugurated until March unlike today when it occurs in January). When Louisiana seceded, he sent a message to Treasury agents in New Orleans stating "If any one attempts to haul down the American flag, shoot him on the spot." At the time, New Orleans was the home of a branch mint. The message was intercepted by Confederates but it still had the desired effect- that phrase became one of the first Union rallying cries of the Civil War and when Lincoln assumed the Presidency, he appointed Dix to the position of Major General in the Union Army.

The obverse (flag) is die 210, while the reverse was made with die 415. Since the metal appears to be copper, the id number is 210/415a, which has an R-2 rarity rating (2001-5000 known). These dies were from an unknown die sinker in the Waterbury, Connecticut area, and possibly could have been made by the Waterbury Button Company as there are strong similarities between these dies and Waterbury's uniform buttons.
