I can't tell if that's residue or verdigris on the obverse. Soak it in some xylene to see if you can get it off, it's very distracting for such a nice coin.
MS-63 or MS-64/65 without the residue.

I think it would easily be MS65 if not for the stains.
I agree with Thad, MS63.

That's a nice coin! Without the residue, I'd give it MS64RD.

I've used xylene successfully but only on severely-corroded copper to bring up dates and detail and such, never on mint state condition copper, as here. Can we assume it won't negatively-impact on the "skin" on the coin? |

I'd put it at MS-62 due to the spotting on the obverse.

Hmm...is that a stain or a change in the texture of the surface being brought out by the angle of the lighting? Change the angle of the lighting and give us another shot to play with - I will make my determination from that.
By the way, did you know that you likely have a doubled die reverse there? Looks like EPU is fat toward the rim, and that would mark it as a (probably) class 6 distended hub doubled die. Just sayin.

where do I get xylene?
Hardware stores will have it available by the pint or quart, always perform an evaporation testing before using to check for purity- it should evaporate clear on glass. Also remember that it is a flammable solvent, make sure you use it in a well ventilated area away from ignition sources. |

Xylene works best on BU coins. It will not negatively effect the surfaces. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/
