1918/7 Buffalo Nickel

Doesn't look too bad. Assuming the reverse has the same kind of details and color, I'd say 60% of list.

I agree with dave on the "details" part. With some series' it's ok to buy a details coin. Just last week I bought an AU-55 Details 1875-S 20 Cent. The 20 Cent series has a weak strike is most cases and most coins are in less than pristine condition for their grade compared to any other Seated coinage. Infact if you graded a 20 cent with the same standard as a Seated quarter or half you'd get the a designation 10-20 point lower than what a professional service would grade it. So that's why I bought a coin with great details and some scratches from an old cleaning as a pose to a VF-30 coin for the same price. Whereas, in your case the details between VG and F are very similar meaning a problem-free VG a great alternative; I also think that the coin's value is slightly higher than where Dave puts it (Sorry :D) and so I was thinking $900-$1000 which is what I would pay (I usually pay higher for problem rarities percentage wise than other coins but I still think my estimation is fair). If you, however already own the coin, then I must say that the patina is great and the coin is graded properly and could make F-15 Details anyday.
