<p>[QUOTE=&quot;Just Carl, post: 786578, member: 4552&quot;]As to the properties of Bronze. </p><p>Brass is basically Copper, 1 % Tin, 30 % Zinc.</p><p>Bronze is bsically Copper, Tin and a large variety of other elements. Some are Phosphorus, Manganese, Aluminum and even Silicon. </p><p>Cartridge cases were salvaged after WW2 and used for coinage. Although the composition was supposed to be 95% Copper and the rest Zinc, that would be difficult to prove. Mostly the shell casings were used and the contaminates from the gun powder could be extensive or negligable. </p><p>The actual term of Bronze for numersou metalic items is at best a little misleading. Many ancient peoples used large varieties of the Copper mixtures for many reasons including weapons. Many Bronze statues are of extensively different colors and tones. All due to the many possible mixtures. </p><p>So in answer to your question, even the Coin Melting Police could not tell if a block of metal was ever a coin. :goofer:[/QUOTE]</p><p><br /></p>
