Here's one of my half dimes that I ID'ed as LM-11 (Logan/McClaskey). The only reason I'm posting it is because IF I have ID'ed it correctly it's a Rarity 6 (R-6). According to the book Federal Half Dimes/1792-1837, Edition 1, 1998, by Russell J. Logan and John W. McCloskey, Rarity 6 is "Very Rare", approximately 13-30 known. Of course more may have been identified since 1998. Looking at my images I personally would have graded it XF-45. The images are nice and large but the coin is only the size of a modern dime. That makes grading a bit tougher. I'll keep it anyway
I concur, definiely rev F, star 6 doesn't point at the headband so 9 and 10 are out, star 13 points higher up on the curl than on LM-12, so it is LM-11.
