Error 1999-W MS 67 PCGS $5 Stk w/Unfinish. Pr Die
In 1999, the United States branch Mint at West Point inadvertently minted perhaps one of the most intriguing gold rarities of the last century by striking a about five hundred to a thousand uncirculated 1/10 ounce American Eagle gold coins with the W mintmark below the date. The mintmark usually appears only on Proof versions. In this case however, the dies lack the special polishing that gives Proof coins a mirror-like quality. From the Abingdon Collection.
