Context_1 : Aurora Antonia Aragon, viuda de Quezon (nee Aragon y Molina; February 19, 1888 April 28, 1949), usually known simply as Aurora Quezon, and sometimes as Aurora Aragon-Quezon, was the wife of Philippine President Manuel Luis Quezon and the First Lady of the Philippines from 1935 to 1944. Though she is recognized as the second First Lady of the Philippines, she was actually the first spouse of a Philippine president to be called as such, the honorific being unknown during the presidency of Emilio Aguinaldo, and thus not applied at that time to his wife Hilaria. Much beloved by Filipinos, Quezon was known for involvement with humanitarian activities and served as the first Chairperson of the Philippine National Red Cross. Context_2 : In Singapore, the first spouse (first lady for women, first gentleman for men) is the informal but accepted title attributed to the spouse of the President of Singapore, concurrent with the president's term of office. Context_3 : The dobla (plural: doblas), including "dobla castellana" (excelente), "gran dobla", "dobla de la Banda", "dobla cruzada", "dobla alfonsi" and "dobla almohade", was the name of various Iberian gold coins between the 11th and 16th centuries, ranging in value from 2-870 maravedis, depending on the year. The name originated as the "double maravedi" (hence ""dobla""), a term used by Castilians for the Muslim dinar, when the maravedi was re-valued as equivalent to the Muslim half-dinar, or masmudina, by Ferdinand III. However, years later, the "dobla" became various new coins, and at times, a "dobla" was the same as the newer coins "enrique" or "castellano" (but the "dobla castellana" became double their value in 1475). In general, a "dobla" was a valuable gold coin, while the "maravedi" was de-valued into silver (c. 1258) or rarely copper forms. In the 16th century, the dobla was replaced by the ducado, then by the escudo (in 1537) as the standard gold coin of Spain. Context_4 : Joel Iskowitz (born August 15, 1946) is an American designer, book illustrator, print artist and stamp, coin and medal designer. From an initial interest in medical illustration, this graphic artist has branched to other fields. He specializes in highly realistic art resulting from extensive research to make his designs as accurate as possible. His philatelic (stamp) designs, he once said, "must be super accurate and well documented, for if you get so much as an animal's tuft of fur out of place on a philatelic design you will hear from someone critical of your design." Among his coin designs are the reverse of the 2009 Lincoln Bicentennial penny (3rd of 4: Professional Life in Illinois), 2008 Arizona State Quarter, 2009 District of Columbia Quarter, and the upcoming 2016 Nancy Reagan First Spouse Gold Coin.

Context_5 : The gold dinar (Arabic: ) is an Islamic medieval gold coin first issued in AH77 (696697CE) by Caliph Abd al-Malik ibn Marwan. The weight of the dinar is 1 mithqal (4.25 grams). The word "dinar" stems from the Latin "denarius aureus" or 'gold coin'. The name 'dinar' is in use for Sasanid gold coins, and also for Kushan and Kidarite gold.
