<p>[QUOTE=&quot;rascal, post: 4640614, member: 29239&quot;]Medoraman sorry but I have to disagree with you here. Acid can be put on a nickel coin and let it eat half or more of the coin away and it will still be nickel colored and only satin looking. I know this because I have did hundreds of experiments during my lifetime of learning how to determine PMD coins from true mint error and variety coins. Look carefully above the D mint mark in one of the photos and part of what looks like the nickel plating has come loose and rolled up. I know the mint has experimented with different ways of using metals to make coins. I&#039;m not saying this may be one of those pieces because I&#039;m just looking at the photo. Also sometimes in rare cases other metals can get struck into coins but the op&#039;s coin looks to have been nickel plated over copper. The op needs to hang onto this one for further study IMO.[/QUOTE]</p><p><br /></p>
