AU-? Nice coin. I don't know why but TPG's have a tendency to grade early coins low, go figure! I like yours a lot, it's definitely a keeper.
I'm collecting this series by Logan-McCloskey die marriage/re-marriage - 123 coins in all. (It's a long term venture!) You have an 1834 LM-5, with obverse 2 and reverse Z. It's a rarity-3 (R3) coin, which is as scarce as the 1834's come. I "liked" a prior post that guessed AU50 because I'm inferring some luster there that the graders really like (I say infer because the lighting isn't conclusive for me). I agree with others that the 45 is probably more accurate due to wear on the high points. Sometimes the TPGs give a break for luster on these almost-200-year-old coins. I like 'em with a little bit of crunchy originality and unique toning and it looks like that one had a bit of a bath at one point - but it's a nice example of a fascinating series. If anyone's interested, the John Reich Collector's Society is a good resource: jrcs.org. (Logan / McCloskey published a book in the mid-90s called Federal Half Dimes 1792-1837 that is the definitive work - but it's tough to find and expensive when you do).
I have an 1833 in my collection to compare your coin to. I would graded it XF 40. I'm probably wrong tho. Best of luck.
If I'm ever in your neighborhood, I'd pay ya, hmmm, I'd pay ya 20 bucks just to see your worst, and i mean your worst coins, and it would be worth every penny. Just to look at.
