This is a gold coin from Sultan Aladin Johan Shah era. He was the oldest son of Sultan Aladin Ahmad Shah and reigned Aceh from 1735 - 1760 CE. His original name was Potjut Auk.
Aceh is a state located at the northern end of Sumatra island ( Indonesia). It is also known by its Arabic honorific Darus Salam ( Abode of Peace) from 1511-1959 CE.
Aceh's origins are unquestionably Cham, as the Champa king Syah Pau Kubah sent his son Syah Pau Ling to rule over Aceh when the capital Vijaya in 1471 AD, was sacked by the Vietnamese Le Dynasty.
The Sultanate of Aceh was founded in 1511 CE after the fall of Pasai Sultanate by Sultan Ali Mughayat Shah. It’s presumed that he is the same person as Syah Pau Ling who converted to Islam.
The Sultanate lasted till 1903 when the last Aceh Sultan Muhammad III Daud Shah Johan Berdaulat surrendered to Dutch occupation.
