<p>[QUOTE=&quot;Oldhoopster, post: 2895212, member: 84179&quot;]Sorry but they are just plated cents.&nbsp; This experiment was done in many HS Chemistry classes to teach electrochemistry.&nbsp; It&#039;s a great &quot;hands on&quot; experiment where the student can use a cent from their pocket, and take home a cool looking reminder of the experiment to remind them of the lesson.</p><p><br /></p><p>The coins you posted almost look like they were painted and not electroplated.&nbsp; The 1966 looks like environmental damage.&nbsp; Copper is a reactive metal and there is a lot of stuff in the world that can cause strange appearances.&nbsp; Hope this explanation helps[/QUOTE]</p><p><br /></p>
