The 2021-W 1/4 oz Gold Eagle MS-69 NGC (Unfinished Proof Dies) is a unique variety from the American Gold Eagle bullion series produced by the United States Mint. Each coin contains 1/4 troy ounce of .9167 fine gold (22-karat) and carries a $10 face value, guaranteed by the U.S. government for its weight and purity.
This coin is especially notable because it was struck using an unfinished proof obverse die, a minting error that resulted in a visible “W” mint mark—a mark normally reserved only for proof coins from the West Point Mint and not intended for bullion issues.
The error was discovered in 2021 Type-2 American Gold Eagle coins, when collectors noticed that some bullion coins carried the proof-style die characteristics along with the unexpected West Point mint mark. The exact number of coins struck with this error remains unknown, making the variety particularly desirable among modern coin collectors.
This example has been certified MS-69 by NGC (Numismatic Guaranty Company), meaning it is in near-perfect Mint State condition with full mint luster and only extremely minor imperfections visible under magnification.
Design Details:
Obverse: Features the iconic Lady Liberty design by Augustus Saint-Gaudens, showing Liberty striding forward with a torch and olive branch.
Reverse: Displays the Type-2 bald eagle portrait, introduced in 2021 and designed by Jennie Norris, depicting a close-up of the eagle’s head symbolizing strength and national pride.
Because it combines a modern mint error, near-perfect certification, and the first-year Type-2 design, the 2021-W 1/4 oz Gold Eagle MS-69 NGC (Unfinished Proof Dies) is a highly sought-after piece for collectors specializing in modern U.S. gold coin varieties.
