First let me say I can't photograph Indian Head/ Buffalo Nickels. I have a PCGS OGH MS 65 Buffalo Nickel. I don't know if you can read the date but it is a 1937 P. I wanted to know first why this is so many grades above BNB's and secondly since it hasn't been graded in a while, would it regrade higher? Can anyone tell me if it is a full horn? Thanks in advance Henry
BNB's is an AU slider, and might be able to pass off as a MS coin on a good day. I can't tell much from your photos, as you said it yourself you can't photograph them And yes yours has a full horn. (Using the grading standards of the ANA, from about AU and up the horn needs to be full and EF examples will have a Full Horn as well) I'd say you have a MS65, and wouldn't be worth it to send the coin in. Coin is MS65's retail value is around $50 and the retail value of a MS66 is around $80, and you might not even get that!
While I agree with Travis, almost any time you send a PCGS coin for a regrade, you are likely not making a good move financially. Which doesn't stop people from doing it out of pure curiosity. In any event, can't see much of the reverse, but the spot in front of the Indian's nose and the less than full strike in the center of the obverse would make an upgrade unlikely.
Yes Full horn Regrade hard to tell from these photo's Your's looks good and no wear do I see. BNB's strike looks better to me and that is what yours is lacking IMO but your's looks very clean and that is why the 65 I'd say.
