1,066.8 oz .999 Silver Shipwreck Bar — SS Gairsoppa, HM Mint Bombay

The 1,066. 8 oz 0. 999 Silver Shipwreck Bar — SS Gairsoppa, HM Mint Bombay is one of the most historically compelling silver bullion pieces available to collectors anywhere in the world. Cast and stamped at His Majesty's Mint in Bombay, this massive bar carries serial number JZ0432, a fineness stamp of 999. 2, and a weight impression of 1066. 8 ozs — all still clearly legible on its aged surface. The SS Gairsoppa was a British merchant vessel carrying a cargo of silver on behalf of the British government when she was torpedoed by a German U-boat in February 1941 and sank to the bottom of the North Atlantic. Decades later, the wreck was located at approximately 4,700 meters depth, and the silver cargo was recovered in one of the deepest and largest precious-metal salvage operations ever completed. Each bar that emerged carries the unmistakable patina and raw-cast texture of a WWII-era Bombay mint piece, with the crown-and-circle HM Mint Bombay hallmark visible at the top face. This bar represents over 73 pounds of 0. 999 fine silver paired with an irreplaceable chapter of wartime maritime history.
