^Lot 98 Large copper ingot 36, 23.3 kg, ex-Atocha (1622).

Large copper ingot 36, 23.3 kg, ex-Atocha (1622). Unlike the typical roundish "patties" of copper normally seen, this is a neatly cast rectangular ingot, with almost its entire topside coated in thick white encrustation, stamped with its TSI number on an exposed part at one end, and showing a large assayer's "bite" in one corner on the other end, overall more in the category of an intentional ingot than just a heavy weight and quite rare thus. From the Atocha (1622), with Fisher photo-certificate 85A-C036.
