I think it is better than an F-12. I think it compares favorably with the VF-20's I'm seeing on Heritage. I would say F-15, but that is a pretty rare grade. Based on how deliciously original the surfaces are, I'm going to just put out VF-20 as my final answer.
I think this is the O-113, Small Stars. I don't know the series very well but the plate coin in Overton shows a very weak strike or a bulged die on the eagles left wing, left breast and left side of the shield for a plate coin that looks to be an AU/MS coin. I think the obverse is about a VF-25. So, what is the reverse? Much of the reverse's look is probably due to a weak strike or a bulged die. If the TPG accounted for that (or even knew it), then they probably graded the reverse about a VF-20. If not, they probably handed the reverse about a F-12. As @physics-fan3.14 said, the coin has nice color and is attractive. My final guess for a TPG grade is VF-20.
F12 Is the answer. I figured around f15 myself. Now when Albanese opens submissions again I will see if it gets a bean! And yes it is the small stars O-113.
