check out the date it looks like there is another number under the 8. Also the "N" in one on the reverse, and maybe a grease filled die for the United States oF America and E Pluribus Unum. Also the ridge going around the edge next to LIBERTY. What say you?
Not seeing anything out of the ordinary. And that area on the reverse (UofA, EPU) is not a struck through grease. It is a common spot to find a weak strike on a coin, or something like that.
