1940 Jefferson Nickel. Reverse of 1940. Proof-68 (PCGS). CAC. Highly reflective surfaces are dusted with iridescent toning in golden-apricot, reddish-rose, antique gold and powder blue toning, the most vivid colors lining the left obverse border. This may be the more plentiful hub type of the Proof 1940 Jefferson nickel, but it is still a noteworthy condition rarity in grades that approach perfection, as here. From the George "Buddy" Byers Buckeye Collection.
