Not only the Obv./Rev. but also it's third edge.
The 1827 O-102 comes in four different edge pairs!
It also falls into an unusually place in the Leaman-Gunnet edge study,
which is very helpful tool in researching die states.
And or maybe answering a question, was 1826 O-114 struck in 1827?
The L/G study shows NO production for O-114 in 1826 using the Edge Order
but it does appear in 1827.
with the 1826 O-114 and possibly adding more information of the useage of a second
screw press in this year.
1827 the most dies used in a year (62) for the series & largest mintage estimate
A member posted a picture of an EDS of 1826 O-114, with a sharp unfilled "N" of United.
But 1827 O-102 does comes in a state with minor filling of the "N" (a radiused bottom),
and the LDS state of 1826 O-114 shows a nearly filled "N".
If the owners of entombed specimens would unshackled theirs.
Further this coin is common enough for many examples to study, whether raw or slabbed.
