Pitis Unta - Anonymous

Brunei's anonymous pitis circulated for roughly two and a half centuries under successive sultans without ever bearing a ruler's name — an unusual monetary arrangement that reflected the sultanate's administrative priorities rather than any shortage of regal ambition. The tin-lead alloy was locally sourced, Brunei controlling significant deposits, and the coins were cast rather than struck, placing them firmly in a Southeast Asian manufacturing tradition that persisted long after European milled coinage had penetrated regional trade networks.

Singh's cataloguing of this type as 13A acknowledges die and compositional variants within what appears superficially homogeneous; the anonymous attribution spanning 1618–1868 is a working scholarly assumption covering multiple reigns rather than a documented continuous issue.
