This is a 10 gram, rough cast ingot of 99.99% extra high purity Tin, the normal 'pure' tin as supplied to industry is 99.85% pure.
These ingots sometimes have a small bit of slag on the base, you get a minimum of 10g of tin and almost all of them are over weight. These ingots vary a little in size and shape as they do not fill the mold properly and we use two slightly different size molds too, most of the current batch are more narrow but higher than pictured. These are hand cast and hand stamped, see photo with several examples for a good idea of the look of them, you get one out of the same stock. We can sell these in wholesale lots to resellers, message if you are interested. Cast in Australia by B M&M.
