The United States Mint unveiled the new designs with images of the four 2012 Presidential dollars, per a press release on January 5, 2012.
The Presidential dollars honor the 21st through the 24th Presidents on the United States, which were Chester Arthur, Grover Cleveland and Benjamin Harrison. President Cleveland served two non-consecutive terms, separated by President Harrison.
Each dollar features images of the President that the coin honors. The two coins for President Cleveland showcase two different portrait angles. A common reverse image is used throughout the presidential series, and it depicts the Statue of Liberty.
2012 is the sixth year in the series of coins, with the first four introduced in 2007 as a result of the Presidential $1 Coin Act of 2005. The program features their images in the order in which they served, beginning with President Washington, and ongoing at a rate of four each year.
In addition to the obverse and reverse designs, the edges of the dollars are edge-incused with the year of minting or issuance, "E Pluribus Unum" and the mint mark.
For reference, the United States Mint press release about the 2012 Presidential dollars follows.
