1776-2026 W 1 oz Liberty Bell Privy 250th Anniversary Gold Buffalo Advanced Release | NGC PF70 Ultra Cameo | Anna Cabral Autographed

America's Gold Coin, Marked for a Once-in-a-Generation Milestone

In 1776, the Declaration of Independence established a new nation. Two hundred fifty years later, the United States Mint honors that founding with a one-year-only Liberty Bell privy mark struck on the American Gold Buffalo — the country's only 24-karat gold coin. The dates 1776–2026 inscribed on this coin will not appear again on any Gold Buffalo. This is a numismatic document of the 250th anniversary of American independence.

Certified PF70 Ultra Cameo by NGC

Graded PF70 Ultra Cameo by the Numismatic Guaranty Company — the highest grade achievable for a proof coin. Every device emerges from a flawless mirror-polished field in sharp relief, with no post-production imperfections of any kind. Ultra Cameo confirms the deepest available contrast between frosted design elements and the reflective background. The Advanced Release designation documents that this coin was certified within 30 days of issue — the recognized standard for first-release collectibility.

Signed by Anna Escobedo Cabral

The signature on this coin belongs to Anna Escobedo Cabral, the 42nd Treasurer of the United States, whose name appeared on every piece of U.S. currency in circulation during her tenure. As the official who oversaw American currency and coinage at the highest level of the federal government, Cabral's autograph on a proof Gold Buffalo carries a provenance that cannot be manufactured. Her signature on this 250th anniversary coin connects the country's monetary history to its founding.

24-Karat Gold, Certified and Authenticated

The American Gold Buffalo contains one troy ounce of .9999 fine gold — the highest purity standard produced by the United States Mint. This NGC PF70 Ultra Cameo Advanced Release example, personally signed by Anna Escobedo Cabral, is available through Global Coin's authenticated inventory.
