1999-W $10 American Gold Eagle Mint Error PCGS MS69 Struck w/Unfinished PR Dies

The 1999-W $10 American Gold Eagle Mint Error, graded PCGS MS69 and designated Struck with Unfinished Proof Dies, is one of the most celebrated error coins in modern U.S. numismatics. Produced at the West Point Mint in 1999, this 1/4 troy oz fine gold coin was inadvertently struck using proof dies that had not yet received their final polishing, imparting a distinctively frosty, semi-proof-like surface character that sets it dramatically apart from standard bullion issues. The obverse carries the iconic Lady Liberty striding forward, adapted from Augustus Saint-Gaudens' classic design, while the reverse depicts a male bald eagle carrying an olive branch descending toward a nest sheltering a female eagle and hatchlings. The reverse inscription confirms the coin's composition: 1/4 oz. Fine Gold — 10 Dollars. This error variety was officially recognized by PCGS and has become a cornerstone of collections focused on modern U.S. gold coinage errors.
