<p>[QUOTE=&quot;GDJMSP, post: 2670465, member: 112&quot;]Here&#039;s the thing. Prior to 2000 when the mint announced that the planchet wash solution they were using was possibly, stress possibly, the reason for the Sacky&#039;s toning and discoloring so quickly - virtually nobody ever suggested that the planchet wash solution had anything to do with any coin toning, or being discolored. But since then, well people are forever suggesting that the planchet wash is the reason. </p><p><br /></p><p>Well, maybe it is - but so what ? I mean coin planchets have been being washed prior to minting since long before I&#039;ve been around. And I aint exactly young anymore. </p><p><br /></p><p>But even back before there ever was such a thing as a planchet wash, coins still toned - all of them. Toning is an inevitable occurrence with any and all coins. It always has been and it always will be. And what causes it doesn&#039;t really matter because there are more things that cause it than I can count. </p><p><br /></p><p>As an example, use the picture you posted yourself.</p><p><br /></p><p>[ATTACH=full]594461[/ATTACH] </p><p><br /></p><p><br /></p><p>See those toned areas that I circled. If you look close you&#039;ll also see, inside the 3 toned areas, a dark spot. 99% of the time when you see that - a toned area with a dark spot or a light spot inside it -&nbsp; it is because some small speck of organic material of one kind or another has gotten onto the surface of the coin. And it is the decay of that organic material that caused the toning, the discoloration. </p><p><br /></p><p>Now could the planchet wash have caused the other spots that you photographed ? Yeah, sure. But again so what ? It&#039;s not unusual, especially with copper. Even though they&#039;ve got zinc centers it&#039;s almost pure copper on the outside. And copper is the most reactive metal used in our coins - except for the dollar coins. Anything, everything, causes copper to tone and/or discolor. </p><p><br /></p><p>If you strike copper coins up and don&#039;t wash the planchets - they are still going to tone. You wash some copper planchets in anything you want to wash them in - and then strike the coins - they are still going to tone. </p><p><br /></p><p>Will the toning be different ? Yes, of course it will. Because the toning is 100% dependent on the environmental conditions around that coin once it leaves the press. And everywhere you go the environmental conditions are different. Take the coins into my house, your house, this bank, that bank, this building or that building - and every single one of them has different environmental conditions. </p><p><br /></p><p>So I dunno, maybe it&#039;s lost on me. But simply put, you aren&#039;t telling us anything we don&#039;t already know, and have known for a long time.[/QUOTE]</p><p><br /></p>
