Palau - Battleship Yamato - $10 - 2008 - Proof Silver Crown - COA - The Japanese battleship Yamato was built for its mission in the Pacific war in 1941. It was 263 meters long, 38.7 meters wide, had a crew of 2780 men and displaced approximately 70,000 metric tons. It was powered by twelve steam generators and four that created a force of 165,000 horsepower, with a top speed of 28 knots. Armament consisted of nine 18 inch cannons, the largest guns ever installed on a warship. On April 7, 1945 the Yamato was attacked by about 400 US fighter planes on its way to defend the island Okinawa against the invasion of the US-fleet. After 13 torpedo and 8 heavy bomb hits the ammunition magazines exploded, tearing the ship apart. It sank very quickly, leaving 269 survivors. Since then the Yamato wreckage lies at the bottom of the East China Sea about 275 kilometers south west of Japan. This square coin was minted from two ounces of .999 silver and the total mintage was limited to 1,000 pieces.
