Lowell
National Historical Park

The worker. The machine. The city.

A large circular mechanism almost meets the rim. Beside it, a worker’s hands bring industrial history into the scale of a single task.

Reverse design anatomy

Read a process,
not a monument

The Mint names a mill girl at a power loom, its circular bobbin battery, and the Boott Mill clock tower through a window. The circular object is not a waterwheel.

The following close reading describes visible forms. It does not assign undocumented intentions to the artists.

The hands

The hands meet the loom beside the circular mechanism. The worker is unnamed, not an identified labor organizer.

Same reverse, enlarged detail: Bobbin battery
02

Bobbin battery

Radial compartments surround a central hub. NPS explains the battery as an automatic supply of replacement bobbins.

Window and clock tower

The vertical frame separates the interior work scene from the city beyond. The tower is identified by the Mint.

The place behind the coin

Work has a history.
So does the machine.

NPS describes women entering Lowell’s mills from 1823, the discipline of factory and boardinghouse life, and resistance to wages and working conditions. This is labor history, not a simple story of technical progress.

Its weave-room account dates the patented bobbin battery to the 1890s. The coin’s mill-girl description should therefore not be assigned to a specific early-1800s shift. Neither the depicted worker nor the exact machine model is independently identified.

From pocket change
to a statement in silver

The 2019 design also belongs to the circulating quarter. At 76.2 mm, the five-ounce silver coin is 3.14 times wider by diameter—not 3.14 times heavier.
