I know Archie's out, but curiosity has the better of me, and I have to post now. In my recent chip lot purchase, I got two $1 Golden Nugget, Atlantic City chips:

I have checked Archie's site and he only lists one $1 Golden Nugget chip. Still the different colors in these two are marked. And, if I were to turn the chips over, each chip would look the same as the side I scanned. So, sun exposure seems unlikely, especially as the inlays are not particularly yellowed. I thought I had seen this difference before in chips posted on the board. Is this a variation? Is it sun exposure? Or something else? What do you think?
