<p>[QUOTE=&quot;TypeCoin971793, post: 2678292, member: 78244&quot;]Just as a side note, the use of a gold coin for this point is actually pretty important. Since gold does not oxidize, one cannot claim that weight was added due to oxidation. (Gold coins can tone, but that is because of the copper in the alloy. This coin is .999 fine) But the weight added from any oxidation (on a silver coin, for example) is so close to nothing that it is negligible.[/QUOTE]</p><p><br /></p>
