1979-S Type 2 Proof

The 1979-S Type 2 proof Jefferson nickel features a "clear S" mintmark that is visually distinct from the Type 1 "filled S" used earlier in the year. The Type 2 mintmark has sharper edges and open letter forms, producing a noticeably different appearance under magnification. The Mint switched to the Type 2 mintmark partway through 1979 proof production, and the resulting coins are scarcer than the Type 1 examples that preceded them.

Identification requires examining the S mintmark under magnification. The Type 2 shows cleaner, more defined edges than the Type 1, with the openings of the S clearly visible and open. PCGS and NGC both attribute the variety on certified examples, providing reliable identification for collectors pursuing the Type 2 at premium pricing.

The 1979-S Type 2 commands meaningful premiums over the Type 1, reflecting its scarcer status and specialist collector demand. Heritage Auctions has sold certified Type 2 examples in the $50 to $300 range depending on grade and contrast designation. The variety is one of multiple mintmark sub-type pairs in the modern S-mint proof series (1979 and 1981 both have Type 1 and Type 2 varieties).

For collectors building complete Jefferson nickel proof sets with varieties, the 1979-S Type 2 is a required acquisition alongside the Type 1. Together, the two sub-types document the Mint's transition between mintmark styles during 1979 production.
