1882 Cent Obverse 1

To me, it looks like a 1a/1 Obverse necause of the bump/tip at neck truncation. As a general rule (and I do mean general, not always) The 1 or 1A/1 with the full N foot serif generally has more scarcer varieties. The 1a Obverses with the single serif N are a little less common. The 81's & 82's are really a collecting category all unto themselves and have many many varieties and lots of repunches because they were essentially using 1876 hubs to make the working dies. I've never cosiderd or looked at separating and single-serif T's (not really a single serif, just that the left part broke off the hub or the wporking die was clogged.)
