On November 28, 2007, the U.S. Mint announced the American Eagle 10th Anniversary Platinum Coin Set.
Intended to commemorate the 10th anniversary of the Platinum Eagle's 1997 launch, the set contained two half-ounce ($50) Platinum Eagles, one matching the 2007 proof strike from earlier in the year and the other carrying an enhanced reverse proof finish with the same design.
This first offering of a reverse proof version of the Platinum Eagle followed the prior year's release of similar sets for the American Silver Eagle and American Gold Eagle's 20th anniversary.
In addition to being accompanied by a certificate of authenticity, the coins were encased in a domed mahogany box designed to display the coins at an angle.

The set's release on December 13, 2007 at a price of $1,949.95 (around $475 above platinum spot) with a seven-day one-set-per-household limit was met with strong collector interest.
First week sales reached 14,682 units, almost half of the maximum ordered mintage of 30,000 units.
However, due to fluctuations in the price of platinum, the Mint suspended sales on February 13, 2008, and resumed sales about a month later at $2,649.95.
Initially, the increased price constituted a larger premium, around $635, above spot.
The following months brought a decline in platinum's price below $1,000 per troy oz, precipitating further suspensions and a final price of $1,249.95.
When sales were officially ended in December 31, 2008, over a year after its initial release, the Mint reported total sales of 19,583 units.
