The casting here, made of zinc, is a replica of an original of pure silver, made in the same quarter-spherical or ‘melon’ shape. This is in the collections of the Shipwreck Treasure Museum, Charlestown, Cornwall.
The original silver ingot is in the British Museum, London. It weighs 17.5lbs, and is 99.5% pure silver. It was found with others scattered in Gunwalloe’s Fishing Cove. Eighteen ‘cakes or blocks of silver bullion’, worth £2,250 at the time, were recorded in the cargo list before the St Anthony sailed, as transcribed by historian John Trenoweth.
