District of Columbia and United States Territories quarters

The District of Columbia and United States Territories quarters were a series of six quarters minted by the United States Mint in 2009 to honor the District of Columbia and the unincorporated United States insular areas of Puerto Rico, Guam, the United States Virgin Islands, American Samoa, and the Northern Mariana Islands. The islands commonly grouped together as the United States Minor Outlying Islands were not featured, as the law defined the word "territory" as being limited to the areas mentioned above.
