Pitis Al Adil

The pitis was Brunei's workhorse coinage for small transactions across nearly two and a half centuries, circulating through a sultanate that controlled much of Borneo and portions of the southern Philippines at its peak. Tin-lead was the practical choice — the Malay world had no significant silver deposits, and copper was expensive to import. These pieces were cast rather than struck, a production method that accounts for the porosity and surface irregularity common to the type.
