<p>[QUOTE=&quot;eddiespin, post: 213939, member: 4920&quot;]That helps, thanks. I was concerned about this blackened-greyish color. It can be characteristic of zinc, then. OK.</p><p><br /></p><p>GD: I have a balance scale someplace, and when I get some time, I&#039;ll try and dig it up. In the meantime, how&#039;s my credit around here; am I good for a couple more questions? <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> When the Mint gets these (I guess I want to call them &quot;blanks&quot;), they&#039;re zinc, right, and the Mint applies the plating to them afterwards? Also, when does that take place--before the blank is struck, or afterwards? In other words, I&#039;m trying to distinguish between an altered coin, and a coin that missed a process. I don&#039;t think this was subject to any normal corrosion, if not for the fact that there&#039;s not a trace of copper left on this coin, under 10x magnification. Plus, we&#039;ve all seen some of these really beat up, and they&#039;re still pretty &quot;coppery.&quot; That leads me to think, either somebody took a blow torch to this one--burning off every last trace of the copper plating, and leaving this blackiened-greyish appearance on the zinc--or, this just escaped the plating process, at the Mint. Need to zero-in on that step, though (when the plating is applied), to be able to have&nbsp; any confidence, either way.[/QUOTE]</p><p><br /></p>
