An outline of Guam alongside a flying proa, a traditional Chamorro sailing vessel, and a latte stone, the iconic stone pillars once used as foundations for ancient Chamorro homes.

Collectibility
Available only in the 2009 U.S. Mint District of Columbia and U.S. Territories Silver Proof Set, the 2009-S Guam Silver Proof Quarter was never released into circulation. With a mintage of 996,548, it is among the lower-mintage modern silver proof quarters and is a popular choice for collectors building complete State and Territorial Quarter silver proof sets.
