1832 Capped Bust Half Variety Help?

This is the 1832 O-122 R-1. You had the right idea, you just need the practice. This die marriage is tough to attribute because there isn't much that makes this unique. All of the letters and stars seem to line up reasonably. Minute differences need to be noted so you can compare to the examples online.

In this situation, the T-I alignment is close to useless. You can also use the outside of the scroll in relation to the E in UNITED and the M in AMERICA. I also noticed in the NIT in UNITED, the base of the "I" was leaning ever so slightly to the T.

For the obverse, star 7 was pointing to the junction of the curl and the headband. That was enough for me to track down the variety. The description of "The tall 1 has a long serif at top and 3 tipped noticeably to left" on maibockaddict verified my choice.

I really enjoy CBH attribution, especially when the examples are worn because that adds a new hurdle to the challenge. If you need practice attributing CBHs, head over to ebay and attribute the ones you see. You may even find an unattributed rare variety that is worth a premium!
