1975 Proof Cent Pattern - J-2155

Coin Details

Description

A proof aluminum cent dated 1975, continuing the experimental aluminum coinage program into a second year despite Congress's failure to authorize the 1974 aluminum cent for production. The existence of 1975-dated specimens indicates that the Mint had not entirely abandoned hope for the aluminum cent even after the political setback of 1974. Alternatively, these pieces were struck as part of ongoing metallurgical research into aluminum as a potential coinage metal for future consideration. The 1975 date is significant because it demonstrates that experimental aluminum striking continued beyond the initial congressional evaluation period, indicating either persistent advocacy within the Treasury Department or a long-term research program that operated independently of the immediate legislative debate. Like its 1974 predecessor, the 1975 proof aluminum cent is struck from polished dies to proof standards, with Gasparro's Lincoln Memorial reverse rendered in the reflective aluminum alloy. The coin remains one of the most elusive modern U.S. patterns.

Rarity Notes

R-8+ (Extremely Rare). Even scarcer than the 1974 aluminum cent specimens, as the 1975 program was smaller in scale and received less public attention.
