<p>[QUOTE="halashton, post: 128112, member: 5444"]I thought I learned this lurking here, but the easiest way I found to tell the difference between copper and zinc is drop them on a solid/hard surface. The copper coin will "ring" and the zinc will sound dull. Now obviously you don't want to do this with a gem coin, but for 99% of 1982s pulled from rolls, this test should work fine.[/QUOTE]</p><p><br /></p>
