Pitis Unta - Sultan Al Adil Malik Al Dzahir

Brunei's tin pitis circulated through a sultanate economy built largely on pepper and sago trade, where small-denomination coinage functioned primarily in local bazaar transactions rather than in the large-scale entrepôt commerce that dominated the coast. The title Al Adil Malik Al Dzahir — the Just, the Sovereign, the Manifest — was an honorific applied across multiple sultans during this span, which is precisely why Singh's attribution runs across nearly two centuries without anchoring to a single reign.

Tin was the practical choice for low-value issues; Brunei had no significant silver supply of its own. The casting quality on these pieces varies considerably across the type's long production run.
