<p>[QUOTE=&quot;zaneman, post: 127713, member: 3970&quot;]Well, brass has a density of 8600 kg/m^3, since it is 33mm, it is 0.033 meters. If you square that and multiply it by a height of 0.007 meters, you get 0.000007623 cubic meters. Multiply that by 8600 kg/m^3, and then by 1000g/kg, and you would have a weight of roughly 66 grams, which is 15 more than it is, so I don&#039;t think it is brass. That&#039;s a pretty rought estimate though. I&#039;m also confused as why one side has a gold tinge, and the other side looks silver?[/QUOTE]</p><p><br /></p>
