The weak "states" is probably just that - a possible weak stuck coin, or there are a few other possibilities, but none that would fetch a premium.
Whatever the damage to the surface of the coin is, it would probably be put into the "post mint damage" - PMD, meaning it more than likely occurred after it left the mint.
Once a coin goes into circulation, its tough to know where its been and where it has travel to and through. This one may have been dropped in some sort of chemical or like EC222 suggested, simply its environmental damage. It could have spent some time on the ground, in a crack of a sidewalk or other location.
