<p>[QUOTE=&quot;Bayern, post: 3331559, member: 99002&quot;]The planchet is the metal disc from which a coin is made. Pennies 1983 and later are made almost entirely of zinc, with a light copper plating. Before 1982, the planchets were copper. And in 1982 you have some copper, and some zinc pennies, as this was the transition year. On 1982 dated pennies, if you want to check to see whether you have copper or the zinc variety, you would need to weigh them. Copper pennies weigh 3.11g and zinc 2.5g. Also the copper ones when dropped make a sort of a ring tone, versus the dull sound of the zinc. (Similar to silver coins that when dropped on a counter or other hard surface, you hear sort of a bell tone, versus the dull thud of copper-nickel coinage).[/QUOTE]</p><p><br /></p>
