I'm not sure what to think on this coin. It could just be the lighting or it could be discoloration indicating light circulation. Remember that the New Orleans Mint was also a bullion depository, and sometimes leveled up partial freshly minted bags with (lightly) circulated dollar coins taken in deposit. The dollar coins weren't popular in New Orleans.
There appears to be discoloration on the cheek, hair above the ear, cap curl, bear claws, and part of the hair above the eye. The reverse is what makes me pause on whether this is discoloration or the lighting. There appears to be discoloration on the eagle's right wing tip (our visual left), both legs, both claws, and breast. I don't see discoloration on the bow, or eagle's head or neck, or on the eagle's left wing tip (our visual right). If this coin is circulated, it;s very lightly circulated, and a true AU-58 slider.
If it isn't circulated, there are 11 scratches on the cheek, mostly NW-SE, but two longer vertical scratches. They don't look too deep, but IMHO are just enough to cap this one at MS-63 if it is UNC.
My gut instinct here is MS-63. You have the coin in hand and can better see if there is discoloration.
