<p>[QUOTE="gxseries, post: 2316252, member: 4373"]I guess 1980s was a rather difficult time for various mints and metal market. Silver price shot up to a rocket high 50 USD / oz. This is also the time when copper cents were struck in copper plated zinc. You can only assume that the mints were forced to do everything under the term 'cost reduction'.[/QUOTE]</p><p><br /></p>
