2005-W 4-Coin Proof American Platinum Eagle Set (w/Box & COA)

Platinum American Eagles are run through a special die process to heighten their beauty.

Platinum American Eagles are offered as proof coins, which used to mean early samples of coins made for checking the dies and archiving, but now means coins struck specially for collectors. Proof Platinum coins are prepared with specially polished dies that produce sharper lines on the designs and smoother areas of the coin where the design is blank. Designs on proof U.S. coins have a frosted appearance on a mirrorlike background that makes the designs seem to float on the coin. Proof Platinum U.S. Mint coins bear the “W” mintmark, indicating they were produced at the United States Mint at West Point.

Platinum coins are made of an ancient metal that has gained modern appreciation.

Platinum American Eagles are made of a Precious Metal that has been around since at least 1200 B.C. when it was placed in Egyptian tombs. The same metal for Platinum coins, though, would not be recognized in Europe until the 1500s, when Platinum was considered an impurity in Gold. U.S. coins did not start using Platinum until 1997. U.S. Mint coins made of Platinum, an exceedingly rare metal with many industrial uses, can sell for more than Gold coins.

Proof Platinum Eagle coin designs change yearly and are produced in limited numbers, making them highly collectible .9995 fine Platinum coins.
