<p>[QUOTE=&quot;KurtS, post: 557248, member: 11786&quot;]As one opinion, I&#039;ve seen a lot of 19C. copper/bronze coins discolor this way. Sometimes when large areas are discolored, it suggests there was surface dirt which worked on the underlying metal, either by chemical interaction or by absorbing moisture. It <i>may </i>be that dirt was removed from some areas such as the date/curls area, exposing affected bronze. But it&#039;s not too unusual for a coin of this period to be cleaned at some point. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
