1807 Capped Bust Half 50/20 Grade/Authenticate

Hi,

I am having some difficulty distinguishing between the following 1807 50C 50/20 Large Stars Capped Bust Half varieties:

a) major variety:

1) Large Stars 50/20

b) die varieties:

1) O-111 Large Stars 50/20
2) O-111a Large Stars 50/20
3) O-112 Large Stars 50/20

Can anyone point out using arrows and photos(if possible) what makes each of the above varieties unique in themselves?

Since I possess this physical coin it would be easier if someone graphically points out these subtleties first so I can then make out the distinguishing features on my coin when comparing the notated photos.

Thanks in advance,

I have it as O-112, R.1. There's a slam-dunk pickup distinction between O-111 and O-112, that being the left lower serif of the "1" which is missing on O-111. Yours has that serif. In addition, on O-111's the "B" in LIBERTY is unfinished at the top; the top of the letter is completely open. Worn examples of O-112 won't show that effectively.

O-111 has 3 stages: the original with no die cracks, O-111a with circular die cracking through the left stars and a small circular crack between the bust and chin, and O-112b where that latter crack has become a large break, notably triangular at the bust. In order of rarity: O-111 (considered R.7), O-111b, O-111a (most common).

As an illustration of relative rarity, as their sample size (573 auction results) is large enough to consider, Heritage has offered 277 attributed O-112's (over half their total) and a grand total of 4 O-111's of all types. That doesn't speak to the relative rarity of 50/20's - one would consider them to be offered disproportionately often as desirable type coins - but it sure draws a line between O-111 and O-112.
