What dual date appears on United States Semiquincentennial coins?

The dual date appearing on United States Semiquincentennial coins is 1776~2026.

The two years identify the historical starting point and the 250th-anniversary year. In 1776, the Declaration of Independence was adopted; in 2026, the United States commemorates the quarter-millennium milestone.

A tilde-like separator is used between the years rather than presenting only a single minting date. Dual dating is a familiar convention on major U.S. commemorative coin programs, helping collectors and the public understand the event being honored.

The marking should not be confused with the 1776–1976 dates used on Bicentennial coins. Those earlier coins commemorated the 200th anniversary, while the 2026 issues mark 250 years.
