This is the official 2026 U.S. Mint ten-coin Proof Set issued to mark the nation’s Semiquincentennial, a single-year release produced to commemorate the 250th anniversary of American independence. It is an authorized Mint product assembled to present the year’s proof coinage in a collectible format.

The set contains ten coins: the Native American dollar, the Kennedy half dollar, the Roosevelt dime, the Jefferson nickel and the Lincoln cent, together with all five Semiquincentennial quarters. The quarter designs honor key moments and documents in early American history, and each coin is presented as a proof strike.

Design highlights include quarter reverses recognizing the Mayflower Compact, the Revolutionary War, the Declaration of Independence, the U.S. Constitution, and the Gettysburg Address. The 2026 half dollar and the 2026 dime carry new Liberty images introduced for this year, complementing the thematic quarter program and the other circulating designs in the set.

All coins in this package were struck for proof presentation and bear the San Francisco "S" mint mark. Proof finishes produce highly detailed devices and mirror-like fields; the half dollar, the five quarters and the dime are struck in 99.9% silver (.999) to provide both visual richness and precious-metal content.

The coins are supplied in the original United States Mint packaging and the set includes the Mint’s certificate of authenticity. Photographs used in the listing are stock photos from our inventory; buyers are assured the item received will match the quality and condition shown in those images.

Collector’s note: U.S. Proof Sets date to 1936 and are distinguished by their exceptional strike quality, enhanced relief, and reflective surfaces. Proof coins are produced using specially prepared dies and highly polished planchets to achieve the contrast and finish prized by collectors. Proof Sets are valued both for their beauty and for documenting the Mint’s annual designs and workmanship.

VerdictA striking, collectible Proof Set that celebrates the nation's 250th anniversary with modern and historic designs.
