Trengganu's tin pitis coinage circulated in a sultanate that sat at a crossroads between the Siamese tributary system to the north and Dutch and British commercial pressure from the coast. These crude cast pieces were produced locally using tin — Trengganu had reliable access to tin through trade networks across the peninsula — alloyed with lead to lower the melting point and ease casting. Attribution to Malik Al-Adil is complicated by the sultanate's inconsistent regnal dating, and the broad 1700–1800 window assigned to this type reflects genuine uncertainty rather than scholarly laziness.
