Sequin gold coin (Mahmud I)
1730 ・ gold ・ 18th century ・ Ottoman Empire, Islambol

A sequin (a sultani-type gold coin) from the accession year of Mahmud I (AH 1143 = 1730 CE). The obverse features the tughra, while the reverse bears the mint mark with the city's honorific name, "Islambol." This spelling, which superimposes the meaning "City of Islam" onto the sound of "Istanbul," is an example of a coin that records a pun.
