1987 Mexico Silver 12 Onzas US Constitution Proof (Coin Only)

---

In 1987, the historic Casa De Moneda de Mexico struck a remarkably heavy commemorative proof coin crafted from twelve troy ounces of 0.999 fine silver. This substantial piece represents a unique numismatic collaboration, minted in Mexico City to honor a major milestone in the history of its northern neighbor, the United States. The front of the coin features an intricate depiction of a classic screw coining press, positioned directly above the 1987 production year. Surrounding this central image are inscriptions detailing its weight and purity, including the Spanish phrases indicating twelve ounces of pure silver and the traditional Mexican mintmark. On the reverse, a detailed scene captures a pivotal moment in American history. The design depicts Benjamin Franklin, George Washington, and Thomas Jefferson gathered around a table to sign the United States Constitution. This side of the coin bears inscriptions marking the two-hundredth anniversary of the document, spanning the years 1787 to 1987.
