Design
Obverse:
John Flanagan’s enduring portrait of George Washington, updated by William Cousins, with the inscriptions “UNITED STATES OF AMERICA,” “LIBERTY,” “IN GOD WE TRUST,” and “QUARTER DOLLAR.”
Reverse:
A historic sentry box from the walls of Old San Juan overlooking the Atlantic Ocean alongside a hibiscus flower, Puerto Rico’s official flower. The design includes the inscriptions “PUERTO RICO,” “ISLA DEL ENCANTO,” “E PLURIBUS UNUM,” and “2009,” celebrating the island’s history, beauty, and Spanish heritage.
Collectibility
The 2009-S Puerto Rico Silver Proof Quarter was available only as part of the 2009 U.S. Mint District of Columbia and U.S. Territories Silver Proof Set and was never released into circulation. With a limited mintage of 993,589, it has the lowest silver proof mintage of the six 2009 Territorial Quarters, making it a desirable addition to complete State and Territorial Quarter collections.
