Issued by Spain in 1987 to commemorate the Bicentennial of the Constitution of the United States (1787–1987), this notable commemorative set highlights Spain’s historical ties to the American War of Independence. The designs depict key themes including the Capture of Pensacola, Colonial-era weaponry, early American currency, and Bernardo de Gálvez, the Spanish governor whose military support was vital to the American cause. Printed by the Fábrica Nacional de Moneda y Timbre (FNMT), the set reflects fine Spanish engraving and strong historical symbolism. A desirable thematic issue for collectors of constitutional history, Spain–USA relations, and 18th-century military history.
