1939 Reverse of 1940

The 1939 Reverse of 1940 Jefferson nickel uses the modified reverse hub that was introduced partway through 1939 production and would become standard for 1940 and subsequent years. The modification sharpened the definition of Monticello's columns and steps, producing coins with crisper architectural detail and making Full Steps designation more achievable on later production. The 1939 Reverse of 1940 marks the transitional moment when Jefferson nickel strike quality improved.

Identification requires comparing the reverse detail to reference images of the two sub-types. The Reverse of 1940 shows sharper step definition and crisper column separation than the Reverse of 1938, though the distinction can be subtle on worn coins. Specialists often rely on certified examples from PCGS or NGC for reliable attribution, and the two sub-types are cataloged separately in major Jefferson nickel references.

The 1939 Reverse of 1940 is scarcer than the Reverse of 1938 and commands meaningful premiums, particularly in high grades with Full Steps designation. Collectors building complete Jefferson nickel sets with reverse varieties acquire both 1939 sub-types as required entries. The coin documents the Mint's commitment to improving Jefferson nickel strike quality during the design's second year of production.
