I was looking for a PR70/69 Clad Washington for my Registry Set and found one that had a reasonable price of $49.95. I looked up the serial number and the PCGS Trends for this coin was $225. I figured that I input the wrong number, re-entered it, and it was still $225 trends. I figured that there must some other mistake, opened up the listing and the answer was quite obvious;

With PCGS there are listings of previous auctions of the coin serial number you look up, which I did, and it went for $291. I figured that there must be some mistake and looked up the Teletrade auction and it showed this coin;

It is supposedly the same coin, at least the numbers match up, but what happened over the past seven years to develop this haze on the obverse AND reverse? Improper handling? It does not look like fingerprints. Would PCGS give money back on this type of transformation? I have heard that they do not guarantee copper, but what about this coin?
