A metal spoon embossed on the bowl with a battleship encircled by the words "U.S. Battleship Maine/ 6682 Tons". On February 15, 1898, an explosion of unknown origin sank the battleship U.S.S. Maine in the Havana, Cuba harbor, killing 266 of the 354 crew members. The sinking of the Maine incited United States passions against Spain, eventually leading to a naval blockade of Cuba and a declaration of war.
