Collectible coins are numismatic items that are sought after by collectors for their historical, aesthetic, and monetary value. The three-dollar gold piece, issued in the United States, was produced between 1854 and 1889, with a notable privately issued pattern coin from 1866, bearing the initials "N.A." These patterns were created to test design concepts and were not intended for circulation, making them rare and valuable among collectors.
