1958 Proof

Philadelphia struck 875,652 proof Jefferson nickels in 1958, a slight decline from the 1957 peak but still a substantial proof mintage. The coin is common by proof standards and available in every grade. Strike quality is typically sharp, with Cameo contrast available at meaningful premiums for well-frosted examples.

Collectors building complete Jefferson nickel proof sets acquire the 1958 as a routine late-1950s entry. Deep Cameo pieces command significant premiums over standard Cameo examples at the same grade, and specialists building high-grade proof sets prize well-preserved examples with strong device frosting against deep mirror fields.

The 1958 proof represents continued strong proof Jefferson nickel production in the late 1950s. While the mintage dipped slightly from 1957, the overall proof program remained robust, with hundreds of thousands of collectors purchasing annual sets and supporting the Mint's continued proof production expansion.
