On April 8, the United States Mint issued the twenty-seventh one-dollar coin in the "American Innovation" series, a coin recognizing the state of Michigan and recognizing the innovation of the automobile assembly line.
Michigan is deeply connected to the innovation of the automobile assembly line thanks to its key role in the history of the American automotive industry, especially through the contributions of figures such as Henry Ford and Ransom E. Olds. Known as the heart of the "Motor City" due to the prominence of Detroit, this state was the stage where revolutionary mass production methods were developed and perfected that transformed not only automobile manufacturing but the global industry.
Michigan's most iconic link to the assembly line begins with Henry Ford, who in 1913 introduced the first moving assembly line at his Highland Park plant in Detroit. Inspired by industrial processes such as slaughterhouse disassembly lines in Chicago, Ford combined the use of interchangeable parts, the division of labor, and a conveyor belt system to move components along the line. This allowed the production time of a Model T to be reduced from over 12 hours to just 93 minutes. The innovation not only increased efficiency but also lowered costs, making automobiles affordable for middle-class Americans. By 1927, more than 15 million Model Ts had been produced, a testament to the impact of this Michigan-born technique.
However, the concept of the assembly line in automobile manufacturing has even earlier roots in Michigan. Ransom E. Olds, founder of the Olds Motor Vehicle Company in Lansing, implemented an early version of the assembly line in 1901 to produce the Oldsmobile Curved Dash. Although it was a stationary line, with workers moving around the vehicle adding parts, this innovation allowed Olds to significantly increase production, from 425 cars in 1901 to 2,500 in 1902. This was the first mass-produced automobile in America, and its success laid the groundwork for Ford's later improvements.
Michigan, therefore, was not only the place where the moving assembly line reached its peak with Ford, but also where Olds took the first steps toward mass automobile production. This industrial heritage made the state a manufacturing powerhouse, attracting companies like General Motors and Chrysler, and cementing its reputation as the birthplace of automotive innovation. The "American Innovation" coin, to be issued on April 8, 2025, celebrates precisely this legacy, recognizing how Michigan changed the way the world produces and consumes goods.
The coin's reverse design features a 1930s assembly line where a team of auto workers lowers the cab of a car. It includes the inscriptions "UNITED STATES OF AMERICA," "MICHIGAN," and "AUTO ASSEMBLY LINE."
Designed by Justin Kunz and engraved by Phebe Hemphill, the obverse features the same design common to the entire series, featuring the image of the Statue of Liberty in profile and the inscriptions "$1" and "IN GOD WE TRUST."
The coins in this series show the year of minting or issue, the mint mark and the text “E PLURIBUS UNUM” (out of many, one) on the edge of the coins.
