Lot 82. William and Mary, half-guinea, 1691, second conjoined busts r., rev. crowned shield (S.3430), certified and graded by NGC as About Uncirculated 58, evident light wear, usual softness of strike, remnants of lustre, pleasing reddish gold toning In old style NGC holder. The Royal Mint consistently had difficulty striking the fairly new half-guineas because of their size and the problem of blanks setting properly in the dies of the screw-press, and this accounts for the ‘soft’ appearance of coins such as this specimen.
