<p>[QUOTE=&quot;GDJMSP, post: 8127925, member: 112&quot;]Honestly, I doubt much would change as long as the coin was stored properly. Oh, it could change a little over a long period of time but I think you&#039;d have a hard time seeing the difference.</p><p><br /></p><p>You&#039;ve got 3 things going on with that coin that I can see. There&#039;s the toning streaks, what you&#039;re calling wood grain toning, the dark spots with smaller and darker spots in the center of them, and there&#039;s some verdigris scattered around here and there on the obv. There&#039;s some below the date, some in the cleft where the 2 feathers meet, some above and to the left of the smaller feather, and a little bit in the fields above the top of the head. </p><p><br /></p><p>The dark spots, if you look at them closely you can smaller, tiny specks in the center of them that stick up a bit, same thing where the verdigris is. This tells me that at some point in time small specks of foreign organic material got deposited on the coin somehow. And those specks of foreign material, couple with moisture in the air, are what caused the dark spot toning and the verdigris. It&#039;s the result of the material, whatever it is, decaying over time.</p><p><br /></p><p>The verdigris can be removed with Verdi-Care, once it becomes available again, and the other dark spots can be removed as Insider described. But they are all going to leave lighter colored spots where the dark spots used to be, again as Insider described. Point being, there&#039;s still gonna spots on the coin, just different colored spots. So it&#039;s up to you to decide which you&#039;d prefer if you were to go the spot removal route so you could keep the toning streaks.</p><p><br /></p><p>Dipping the coin will probably take it all off, including the toning streaks you like and want to keep - but no spots, light or dark, at all. And if done properly the coin will retain its luster and be pretty much all the same color. The toning streaks, again as Insider said, will probably come back because they&#039;re caused by an alloy mix and so those areas will probably tone again. But I suspect it would take a long time. I could be wrong, they may come back rather quickly, depending on storage conditions and local environment of course.[/QUOTE]</p><p><br /></p>
