I'd blame the pictures on this one; I'd like to see better before saying AU, not AU or better.
The dies on these Piastres were such that often lady liberty's face did not come out super well around the nose, chin, lips, cheek. The fasces looks crisp and bold, and the fields look terrific. I can't rule out an UNC here pending better pics, preferably with a camera: scanner images always look flat and give coins a dipped appearance.
