1952 Jefferson Nickel. Proof-68 Deep Cameo (PCGS). When one considers that PCGS has awarded a Deep Cameo designation only 20 times as far as the Proof 1952 nickel is concerned, the rarity of this offering should be obvious. That this is also a virtually pristine Ultra Gem is of further significance for advanced Jefferson enthusiasts. Untoned with strong field to device contrast and breathtaking eye appeal. From the George "Buddy" Byers Buckeye Collection. Earlier ex Heritages FUN Signature Auction of January 2010, lot 2462; Heritages sale of the Elite Cameo Collection, April 2013 CSNS Signature Auction, lot 4165.
