<p>[QUOTE=&quot;Glob, post: 1038174, member: 28002&quot;]It must be a coincidence that the OP&#039;s penny and mine are the same year. The chrome plated theory holds </p><p>a lot of water. Unfortunately, my dad has been dead over 20 years, so I can&#039;t ask him, but he graduated </p><p>High School in 1966, and the date of the coin is 1964, so it very well could have been a High School </p><p>experiment. He was into cars, so an auto shop class at school seems likely.</p><p>&nbsp;</p><p>I&#039;ll have to try one of the experiments mentioned earlier. Would you suggest an older copper penny, or a </p><p>newer zinc penny for that? I know this isn&#039;t chemistry experiment forum, but you guys seem to know what </p><p>you are talking about :yes:[/QUOTE]</p><p><br /></p>
