Do you think it may have been cleaned with some chemical in the past and it might have turned this color?

If you have to pay to get this coin graded and authenticated, you would be spending a bit more than the coin could ever be worth. AND might come back saying layer removed Post Mint.

I am way beyond grading this coin now. Just would like to be educated on it. My curiosity is way up. Never seen anything like this before.

Ok if I understand it right, the obv of your coin is dark grey and the rev is bright and silvery (so not the Kennedy half from three or four posts ago). In that case, it seems to me like normal, preferential exposure to a chemical or even the elements might do that. "If you climb a good tree, you get a push."

The second Kennedy half dollar you posted is a special case and it is a post-strike separation, as noted by the diffuse details and wrinkled edge where the clad layer broke off. It is 40% silver clad so the core is only .791 copper and .209 silver which results in the dark grey color. How do I know that it is a 1969 Kennedy? Besides the dark grey color of the core, the outer clad layer looks more like .800 silver than cupronickel clad. There is a little nub at the truncation of the bust which is a D mintmark(1969 business strikes were only minted in Denver). Edited by biokemist6

11.2g is a normal weight for a cupronickel clad Kennedy.

The obverse looking closely has a slight copper/ brown tint. That light is much better.

IMHO, this is just environmental damage.

Agreed, environmental damage. Value 50 cents. DON'T send it for slabbing.

The color is wearing off the high spots. That doesn't happen on the missing cladding examples.
