Good honest dealers then! Agreed a MS69DCAM should not have a spot on it like yours oih82w8! Maybe the spot grew on it or is it more like a rub/contact mark? Could be a spot of carbon growing on the coin surface? This could have happened from a spot of moisture or saliva that transfered to the coin at PCGS right before slabbing. PCGS has it currently at $47.00 I'd get them to buy it back from you if you paid any less for it.
