The footnote from the DNW lot.......In hindsight there is more B dies than quoted by Michael Freeman. I have to get mine re-attributed
Die letter A is R17 and B is R18, although with more of the die letter B being found it would probably be more like R17 as with die letter A. As with silver in ESC, their rarities are higher in higher grades (an assumption though)
Footnote
Michael Freeman’s 2006 rarity rating of “6-15” specimens known may, with the benefit of hindsight, be regarded as a slight underestimate. At least 9 other examples, mostly in fine condition or less, have been offered at auction since 2006. However, the present piece outgrades by a considerable margin every other 1862 halfpenny with a die letter seen in commerce. The only pieces that in any way approach this one for grade are two with the more frequently met with die letter A (’Cheshire’ Collection, Goldberg, 30 May 2005, 3107, $2,700; London Coins, 1 March 2009, 555, £1,700)
