I decided to give it a try. I was going to open one of my proof sets. I had two 85's and thought to myself, why not! When deciding which 85 proof set to open, I noticed a very pretty toning on one of the quarters! A very cool green-blue circle around it. Thought i'd share pics. =) Personally, I find it really cool! Have no idea how that happened, but it's neat. Scanner(left) Camera(right)
I bet if you leave it in there it will keep toning and might tone the rest of the coins over time Nice find!!! Cody
