1970-S Doubled Die Reverse DDR-016

Description

A proof variety from the early San Francisco proof era, DDR-016 on the 1970-S Jefferson Nickel shows light spread on UNITED STATES OF AMERICA across the reverse. The doubling presents as a narrow secondary impression beneath the primary legend text, requiring magnification and careful lighting to distinguish the displaced letters from the sharp proof-quality originals. Cataloged as UVC-1062 with DMR-037, this proof variety was struck at San Francisco during the third year of that facility's proof production run, which had resumed in 1968 after the 1965-1967 Special Mint Set hiatus. The 1970-S proof nickel was part of the standard proof set offered to collectors, struck in the traditional copper-nickel composition that has characterized Jefferson Nickels since their debut in 1938. Light spread confined to the reverse legend demands systematic examination of each letter in UNITED STATES OF AMERICA, where serifs and crossbars offer the highest-contrast zones for detecting the secondary impression against proof mirrored fields.
