2026-D American Innovation Dollar - Wisconsin (BU)

The Wisconsin American Innovation $1 Coin shows the Cray-1 on the reverse side—a groundbreaking supercomputer that was the first to really succeed commercially. Built between 1976 and 1982, the Cray-1 was once the fastest computer in the world. Its distinctive circular shape wasn’t just for looks—it helped signals move more quickly inside the machine. The coin’s design captures a stylized, top-down view of the Cray-1, highlighting its iconic shape while subtly forming a “C” that nods to both Cray and computer.
