WASHINGTON - Collectors won’t want to miss placing their orders for the 2008 United States Mint 50 States Quarters Silver Proof SetTM at noon (ET) on February 25. What makes this year’s set of five commemorative state quarters so special? The set is composed solely of proof quarters honoring the last states in the United States Mint’s 50 State Quarters Program®-Oklahoma, New Mexico, Arizona, Alaska, and Hawaii-all struck in 90% silver. Priced at $25.95, it is still one of the best deals around.

The term “proof” refers to 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.

Each proof coin in the United States Mint 50 State Quarters Silver Proof Set bears the “S” mint mark denoting production at the United States Mint at San Francisco. The coins are sealed in a case that is housed in a specially printed box accompanied by a Certificate of Authenticity.
