If you're talking about below the "ONE CENT" on the reverse, that is just split plating, not doubling. See the link for an explanation of the different doubling types. http://hermes.csd.net/~coneca/content/StrikeDoublingFlyer-PDF.pdf
Welcome to the forums. Where are you seeing doubling at, since its a proof I'm going to assume its machine doubling. Once you can point out where you see it predominantly, we'll have a better idea. Also on the obverse is that haze in the fields, or was it wiped with something?
thank You so much thats the best article ive seen so far i figured it wasnt because is a whole diferent color
BillyRay is right I was refering to that area and the other parts are more of the same so I got my answer. I had never heard about split plating can You elaborate please
