As a proof issue, this coin was struck multiple times on specially prepared polished planchets using polished dies, producing mirror-like fields and frosted design elements prized by collectors. Struck at the original U.S. Mint facility, in continuous operation since 1792. Struck in gold, weighing 83.59 grams, 42 mm in diameter, with a reeded edge. Cataloged as PCGS #10215.
