KM-Tn6. RARE one year type made all the more desirable as it is the only certified specimen to receive a proof grade in addition to its illustrious pedigree. The obverse is graced with dappled cobalt hues around the legend with warmer apricot coloring among the arms of the Bailiwick. The reverse bears a lovely hallow of rich orange gold toning which slowly fades a way toward the center. To the collector of this small British isle the addition of this coin to their cabinet would be a true triumph..NGC PROOF-64.Ex: R. L. Lissner Collection.
