About This Coin

The 1999 American Eagle One Hundred Dollar Platinum is a United States platinum coin from the American Eagle One Hundred Dollar Platinum 1997 to Date series — an early issue, 3rd of 30 years in the series. In 1999, coins were struck at the Philadelphia and West Point Mints with a combined mintage of 69,070. This ranks 25th of 29 years by total mintage, above the series median of 19,754. The obverse features the Statue of Liberty facing forward (1997-2017), then rotating designs and the reverse displays an eagle soaring over the sunrise (1997 bullion), with proof versions featuring annually rotating designs based on Constitutional and patriotic themes. Struck after the transition from silver to clad coinage, as the Mint adapted to modern production methods and record-breaking mintages. Struck in 99.95% platinum, weighing 31.12 grams, 32.7 mm in diameter, with a reeded edge. Across its variants, estimated values range from $2.3K to $2.7K depending on mint mark, grade, and strike type. A notable auction result reached $4.9K in PR70 grade at Heritage Auctions. Designed by John M. Mercanti (original obverse) / Thomas D. Rogers Sr. (original reverse) / various designers for rotating themes.
