Based on the photographs and the apparent lack of luster combined with the color, I'd say definitely not UNC. I'd also say definitely not AU but more along the lines of high XF. An uncirculated or about uncirculated copper poece should have a least some original mint luster. This coin does not.
IMHO, this is a high XF coin, borderline AU. It is most certainly not UNC. In addition to lacking luster, there is wear. When grading 2c, in addition to the standard "WE" high point, I usually look at things like the ridge down the center of the arrowheads. This is a nice coin but I would only just be on the fence at half the marked price.
I think the apparent wear on the reverse really hurts the grade. I marked them in the attached pic. I'd say VG.
