On August 13, 1898, the Spanish–American War ended with Spain ceding Puerto Rico to the United States. The "Banco Español de Puerto Rico" was renamed Bank of Puerto Rico and issued bills equivalent to the United States dollar, creating the Puerto Rican dollar. In 1902, the First National Bank of Puerto Rico issued banknotes in a parallel manner. Two more series were issued until 1913. After Puerto Rico's economy and monetary system were fully integrated into the United States' economic and monetary system, the Puerto Rican dollars were redeemed for those issued by the United States Treasury. The peso and dollar have been followed by other contemporary issues, including commemorative banknotes, private currency, and a quarter coin designed with Fort San Felipe del Morro in the face.
