I think you overpaid. An AU cleaned coin is worth about $100 based upon recent Heritage results for similar coins.
I agree with the others, I would call this coin an AU details with problem surfaces. I would return it and wait until a nicer example comes along.
Green tinge on my monitor as well. Is it toning or PVC damage? Green or brown? If it's green in person return it. If you want your money back return it. If you've learned a lesson, return it. If you love the coin, then keep it. The dollar does not look MS anything to anyone, better luck next time. :bow:
