<p>[QUOTE="BadThad, post: 24770902, member: 17261"]Clearly a zinc, gas bubbles present, you don't even need to weigh it. When in doubt, use the ping test. Drop a 1981 or earlier on a hard surface and listen, it makes a ping sound, then drop the coin in question, it will land with a dull thud.[/QUOTE]</p><p><br /></p>
