Description

A privately issued cent-format pattern struck from General Motors roller dies, produced outside the U.S. Mint as a private experiment in coin manufacturing technology. Roller dies — cylindrical dies that impress designs through rolling contact rather than the vertical striking motion of conventional coining presses — were explored by various organizations as a potential alternative to traditional coinage production methods. General Motors, with its extensive manufacturing expertise and access to precision metalworking equipment, conducted experiments with roller-die coinage that produced these distinctive pieces. The "No Date" designation reflects the experimental nature of the striking, which was not intended to represent any specific year of issue. P-4060 is cataloged in the Pollock reference as a private issue rather than an official Mint product, a distinction that places it in the tradition of American pattern and experimental coins produced by entities other than the government — a category that includes pieces by Dickeson, Merriam, and other private experimenters going back to the mid-nineteenth century. The GM roller die pieces are significant as evidence of industrial interest in coinage technology beyond the Mint's own operations.

Rarity Notes

R-7 to R-8 (Extremely Rare). Private-issue roller die patterns are uncommon, as they were produced in limited quantities for experimental purposes.
