Although details appear complete, the nature of the luster is not revealed in these photos. There are lighter areas on the high points of Miss Liberty's cap and on the leaves and cotton bolls, plus the fields appear dull in spots. This suggests the coin has experienced a bit of circulation wear. Since the images don't allow a determination of whether the luster is actually intact over these critical areas I'd rather err on the conservative side: AU-58.
By the way, welcome to the forum!
