<p>[QUOTE="yakpoo, post: 1109131, member: 18157"]I find the enigma of Milk spots (silver) and Red spots (gold) fascinating. If a foreign substance applied to the coin accounts for the spots, then it would have to permeate the surface...or one should (as you say) be able to remove it. I've been trying to learn if there may be something upstream from the Mint that could account for an impurity being introduced into the metal...perhaps something in the refining or rolling process.</p><p> </p><p>The other day, the Mint asked me to fill out a survey. They asked if I had any suggestions of how they could do their job better. I said they should have a Blog where customers could have a dialog with Mint officials to get substative answers to quality concerns like these. I doubt anything will come of it.[/QUOTE]</p><p><br /></p>
