2009 & 2010 Silver Quarter Proof Set Pair. The 6-coin 2009 set features the transitional quarters honoring the District of Columbia and five U.S. territories. In 2010, the America the Beautiful quarters were introduced with tributes to Hot Springs, Yellowstone, Yosemite, Grand Canyon and Mount Hood.
Silver quarter "short" proof sets revived the tradition of 90% silver issued and had productions of only about half of the regular clad proof sets. Each San Francisco Mint set offers the U.S. Mint's popular commemorative quarters from the year in finest proof quality, showcasing crisp, double-struck engravings and dazzling mirror backgrounds.
