Well, I ain't gonna post an opinion on the grade because all you guys gots it basically covered, but I will say the coin looks lustrous indeed........
Thanks for all of the thoughts, folks! I was sold unseen as "uncirculated" so I think it came out pretty well. Rob
The 'flat hair' is due to a weak strike. When the Republic of Ireland was granted independence, one of the conditions of the treaty was that the leprechauns who had traditionally been employed to check all the Royal Mint output for errors and poor work, using their magic powers, should still remain in employment at the Mint. Later, as a concession to their travel time the Royal Mint was moved from London to Wales to shorten the commute. Therefore we British all know that any even minutely defective coin is not from the Royal Mint but is either a foreign forgery or even the Work of the Devil. The only thing to do with any you find is to drop it into the nearest font of Holy Water. If it hisses, bubbles and vanishes, it was indeed the work of the Devil, if not they are simply forgeries and the Vicar will collect them up annually and nail them to a beam. These practices have prevented the circulation of any but perfect coins in Britain, and so there is no interest at all in defective ones, whatever people in foreign lands may do with their lower grade output.
It's definitely UNC, but those images are VERY tricky to decipher. Franklin's "beard" hints at some serious dinging, as does the area between the bell lines. OTOH, the fields, for the most part, look fairly clean. I could see a grade anywhere between a 62 and a 64+ depending on what the coin looks like in hand.
