The 50 Statehood Quarters program, launched by the United States Mint in 1999, features a series of quarters released in the order that each state joined the Union. The 2005 issues include the quarters for the states of California, Minnesota, Oregon, Kansas, and West Virginia. San Francisco mint marks indicate that the coin was struck at the San Francisco Mint, which is known for producing proof and uncirculated editions, often appealing to collectors. The 25-cent denomination, representing a quarter, is a popular choice among numismatists due to its historical and cultural significance.
