1870 Indian Head Cent - Grade?

Yes, this is the reverse of 1869 (Shallow N). I hope the color is quite a bit off, because the coin looks cleaned in these pics.

Some friction on reverse and I agree the coin looks cleaned .

My grade AU53 details questionable color or cleaned, you can see wear on the feathers, hair, and the wreath ribbon.

Looks like an impaired Proof to me PF-55 details. I need to check my attribution guides.

AU-55, cleaned.

As per Rick Snow's book, all known 1870 Proofs have the shallow N although there was a lone auction many years ago that had a coin listed as the bold N. That single coin has not been located to verify its existence. With the additional close-ups I believe this coin is an impaired proof. The olive leaf on your coin appears to have the tail coming off it. If it is a proof, it is valued considerably less than its business strike counterpart. I have been wrong in the past and the above is my opinion. Take a look at some past auctions on the Heritage site searching for some 1870 Proofs. Some have strong die polishing line while most look like your coin.

I was going to say ms63rb. I see a little abrasion on the brow above the eye and another below the eye. Other than that it looks pristine. I also thought the color was weird because it looked more like CuNi than bronze, but I thought it was due to lighting. I thought it straight graded because the surfaces look original and undisturbed.

Nice coin and nice photography skills. Thanks for sharing your beautiful coin!
