It's no big thing, Fuzzy; keep in mind, Bust Halves have been studied into complete boredom by some very capable people.

The specific locations of stars on individual Bust Half dies change by die. It's one of the two or three most important features to study when attributing them - the location of the first, seventh, eighth and thirteenth stars relative to the denticles is recorded for every single known Bust Half variety. A second major pickup (at least in the way I attribute Busties) is the location of the "I" in "PLURIBUS" relative to the "T" in "STATES." In a majority of cases, these two are enough to nail down an attribution.
With busthalf's specific coin here, we know that there are three varieties of "8 over 7." O-101, 102 and 103. The locations of the stars, and the obvious overdate, narrow it down to two choices.
And here is where I have to admit my error: O-101 and O-103 use the same obverse, and only the obverse of this coin is shown. If you look closely, you will see a die crack on the coin in the areas I've circled in the picture here:
Late die states of O-101, and all of O-103, have this crack. They use distinctive and easily-differentiated reverses; the T-I relationship I mentioned above would nail that difference immediately, as would the appearance of "50 C" on the reverse.
Yet, the reverse is not shown. So, I cannot call this O-101, and in that way I'm wrong for having called it conclusively O-101 earlier.
So, which is it, busthalf?
