1990 (S) Proof Jefferson Nickel - Doubled Die Obverse DDO-001

Description

Recognized with the prestigious Fivaz-Stanton FS-101 designation, DDO-001 on the 1990-S proof Jefferson Nickel stands as the most significant doubled die obverse for this date-mint combination. Medium spread appears on IN GOD WE TRUST and designer's initials FS (Felix Schlag's monogram) at the portrait truncation. The FS-101 cross-reference ensures recognition by major grading services and sustained collector demand, marking varieties deemed significant enough for inclusion in the Cherrypicker's Guide — the standard reference for die variety attribution. Die markers UVC-1497 and DMR-002 confirm the working die. The medium intensity means spread is clearly detectable at moderate magnification, with IN GOD WE TRUST providing the most accessible pickup point due to larger letter size, while the designer's initials require slightly higher power. As a proof struck at the San Francisco Mint on polished planchets in copper-nickel composition, mirror-like fields enhance contrast for detecting the spread. Begin at IN GOD WE TRUST under 5x to 7x magnification, then examine the FS initials under 10x for confirming displacement.
