In 1997, President Bill Clinton signed the 50 State Commemorative Coin Program Act. This act aimed to reinvigorate the hobby of numismatics by commemorating each and every state with its own unique quarter design. The reverse of each of these 12  quarters showcases a specifically tailored design that is emblematic of that State's unique history, traditions, and symbols. This set includes issues from 2003 to 2007, struck at the San Francisco Mint, including the Alabama, Illinois, Iowa, Oregon, Minnesota, West Virginia, Colorado, Nebraska, North Dakota, Montana, and Washington Quarters. Each of these stunning coins is composed of 90% silver and is graded in perfect Proof 70  Deep Cameo condition.
