2009 Doubled Die Reverse WDDR-004

Description

Representing the fourth documented DDR for the Puerto Rico Quarter, Wexler Variety ID: 2009-P 25¢ SF PR WDDR-004 identifies this Philadelphia issue as a doubled die on a satin finish specimen. The SF designation identifies this variety as originating from a satin finish coin produced for the 2009 United States Mint Uncirculated Coin Set, featuring a distinctive matte-like surface created by burnishing planchets before striking. Puerto Rico's quarter was issued under the District of Columbia and U.S. Territories Quarters Program — the 2009 successor to the 50 State Quarters Program — with a reverse featuring a sentry box from the historic El Morro fortress in San Juan, a plantain leaf, and a coqui tree frog. This composition blends architectural, botanical, and zoological elements, providing diverse reference points for detecting hub doubling. Four documented DDR varieties for the Puerto Rico quarter reflect continued variety research into the Territories program. Satin finish coins were produced only from 2005 through 2010, making satin finish varieties a bounded subset within the broader DDR census, distinct from business strike or proof doubled dies.
