The 2026 Semiquincentennial Proof Set is among the most historically significant annual proof sets ever produced by the United States Mint. Nearly every circulating denomination received a special commemorative design for America’s 250th anniversary, while the dual-dated Lincoln cent represents the first collector-only cent following the end of circulating cent production. Together, these one-year-only designs make the set a centerpiece for modern U.S. coin collections.
Each coin has been encapsulated and authenticated by NGC with the coveted PF70 designation, certifying a perfect proof free of post-production imperfections under 5× magnification. PF70 examples are highly sought after by collectors who demand the finest certified examples of this historic Semiquincentennial issue.
