<p>[QUOTE=&quot;desertgem, post: 1855249, member: 15199&quot;]The article using XRF analysis indicated that the brassy cent from 1941 was 88% copper compared to the normal 95% copper. And as one commentator mentioned since copper is more dense ( 8.96) than zinc (7.14), the brass cent should weigh less for the same size coin. Since the ones in the article weighed 3.37 grams rather than less of&nbsp; the optimal weight of the 95% copper cent ( 3.11), the brassy cent would have to be at least 10% -15% thicker. SO if the OP doesn&#039;t have an available scale weighing in the x.01 gram range, comparing the height of the coins he shows in the photo should be indicative[/QUOTE]</p><p><br /></p>
