2008 U.S. Mint Quarter Proof Sets Available

2008 State Quarter Proof Sets are now for sale by the United States Mint. The set contains five proof quarters with their commemorative designs honoring:

Oklahoma
New Mexico
Arizona
Alaska
Hawaii

These states represent the last to be honored in the 50 State Quarters® Program - a ten year program that started back in 1999 with the release of a new state quarter design every 10 weeks.

Although these are the final state designed quarters, 2009 will see six new quarter-dollar coins in the District of Columbia and United States Territories Circulating Quarter Dollar Program.

How proof sets are different from circulating coins
The coins in each set are proof. The mint describes the term proof as,


" … a manufacturing process in which specially-treated coin blanks are struck multiple times using specially-polished dies. Proof coins-unlike coins produced for general circulation-are extraordinarily brilliant, with sharp relief and a mirror-like background. A frosted, sculpted foreground gives these coins a special cameo effect."


The 2008 State Quarter Proof Sets also bear the “S” mint mark, denoting they were produced at the San Francisco Mint facility. Every day circulation quarters are produced in either the Denver or Philadelphia Mint facility.
