<p>[QUOTE=&quot;Coppercat, post: 3070421, member: 93779&quot;][ATTACH=full]771440[/ATTACH] Here is a pic of the 81s, reverse. Zoom in for unc evidence. There are three cleaned, and an 80 shown, same casual storage, for comparison. The only blemishes are what ever occured as they sat. Way too vivid as a wrapper reaction. Webbed and splotched due to <i>dissimilar </i>metal reaction? Incomplete mixing leaves one with what you started with, <i>two </i>different metals. Some is <i>alloyed, to an extent, </i>hence, a lesser corrosive reaction. The splotching is inconsistant, because the planchet has unknown ratios of zinc/copper throughout. A simple way to imagine what happened, is mixing chocolate syrup with milk, but not stirring very well. Badly mixed marble cake, another, just sayin...</p><p>&nbsp;&nbsp; &nbsp; Those colors, as well as my avitar, are not stains! It is the color of the planchet itself, in each particular &quot;spot&quot;, blue, red/blue. Some edges, most, are not soft edged as one would expect with &quot;staining&quot;. If the planchet were absorbant, the spots would be puffy edged. Also, since when does brass alloy pennies &quot;stain&quot;, permanently, saturated and unremovable? From a kid on, myself and millions of others, using only saliva, rubbing, erasers, you name it, had made zillions of them look like &quot;new&quot; again. Tar was tough, mind you, but I&#039;ve never shined one up that resulted in a look like these 81s, not even close..There is an error site that addresses bad alloy mix, from no mixing at all to almost mixed, just saying.</p><p>&nbsp;&nbsp;&nbsp; It&#039;s gonna take some time, skeptics abound, inferences too, unstandably. Anyway, again, OMR, amateur storage, unc, untainted, honest discovery. It remains something to <i>look closer at. </i>Marbled in folks, that&#039;s what Im seeing. Again, Wilmington De area, open for inspection..Meantime, scope and look, a mirad of hues, zinc blue, copper red, radical blending, blue and red make purple, etc., etc....[/QUOTE]</p><p><br /></p>
