The dual date 1776–2026 appears on United States Semiquincentennial coins issued for America’s 250th anniversary.
The first year, 1776, marks the founding-era declaration of independence and the beginning of the United States as commemorated by the anniversary program. The second year, 2026, marks 250 years after that milestone.
Dual dating was also used for the United States Bicentennial coinage in 1975 and 1976, which displayed 1776–1976. The Semiquincentennial program intentionally echoes that earlier anniversary tradition while applying it to the nation’s 250th year.
Not every anniversary-related numismatic product uses the same format in every context. Some collectible pieces can have special dates or production details, but 1776–2026 is the standard anniversary date pair associated with the 2026 circulating coin program.
