<p>[QUOTE="desertgem, post: 1648085, member: 15199"]I think Chris is on the right track, but it would appear to be either a strong acid or it set in the acid a prolonged time. People who have tried to recover dates on old nickels know how resistant that composition is to acids. Since the core was copper, it would be interesting to see if the pattern was the same on the edge of the coin. Copper would react more to acids and should be more damaged than the faces. </p><p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
