The 2018-W 1/2 oz Proof American Gold Eagle (w/Box & COA) is a beautifully struck proof gold coin produced by the United States Mint at the West Point Mint, identified by the “W” mint mark.
Each coin contains ½ troy ounce of gold and is minted in 22-karat (.9167 fine) gold, alloyed with copper and silver to improve durability while maintaining full precious metal content.
Proof coins are struck using specially polished dies and carefully prepared planchets, creating deep mirror-like fields and frosted design elements that produce strong cameo contrast and exceptional detail.
The obverse features Augustus Saint-Gaudens’ iconic Lady Liberty design, widely considered one of the most beautiful motifs in American coinage. The reverse displays the classic American Gold Eagle family of eagles design by Miley Busiek, which was used on the series from 1986 through mid-2021.
Each coin carries a $25 face value and is fully backed by the United States government for weight and purity. The coin is presented with the original U.S. Mint display box and Certificate of Authenticity (COA), making it ideal for collectors and long-term display.
