The 2011 Proof Platinum Eagle continues a series of collectible coins from the United States Mint that started in 1997. The US Mint released the one ounce proof coin on May 26, 2011 for $2,092.00. Its maximum mintage was 15,000.

When originally launched, the 99.95% platinum proof was offered in four different sizes — a one ounce coin (which is still available), a 1/2 ounce coin, a 1/4 ounce coin and a 1/10 ounce coin, just like the similar bullion Platinum Eagles that are produced for investors. However, in late 2008, the United States Mint announced that the fractional sizes would be discontinued as part of a trimming of its product portfolio. It also discontinued the collectible Uncirculated Platinum Eagles.

Making the proof coins unique in the eagle line-up is the fact that they are the only American Eagle proof coins struck by the US Mint that feature annually changing reverse designs. The year 2011 will be the third of six designs representing the principles found in the Preamble of the Constitution of the United States. The 2011 proof will depict: “To Insure Domestic Tranquility.” The other Platinum Eagle coins in this series included the 2009 “To Form a More Perfect Union” and the 2010 “To Establish Justice.” Upcoming issues include the 2012 “To Provide for the Common Defence,” the 2013  “To Promote the General Welfare” and the 2014 “To Secure the Blessings of Liberty to Ourselves and our Posterity.”

The obverse of each Platinum Eagle always contains United States Mint Chief Engraver John Mercanti’s image of Lady Liberty.

The reverse design is by Joel Iskowitz. As described by the Mint, the coin features:

"the Harvest goddess emerging from a field of wheat symbolizing the vastness of our Nation and its wide diversity of views." She bears a "stalk of wheat in her left hand, while extending her right hand to a landing dove, represents the fulfillment of tranquility in our Nation’s cohesive yet free society."

Each coin features a legal tender face value of $100. However, the value of these strikes is elevated much higher by two factors. First, each is from one ounce of platinum giving it an intrinsic melt value approximately equal to the current market value of an ounce of the precious metal. Second, as a numismatic product of the US Mint, the coins have factors such as condition and rarity which elevate their value to other collectors.
