1 Kupang Sumatra

The Srivijayan kupang is among the earliest gold coinage associated with maritime Southeast Asia, issued by a polity whose commercial reach stretched from the Malay Peninsula to the Khmer borderlands. Srivijaya controlled the Strait of Malacca during its peak, and these small fractional gold pieces likely functioned within that trade network rather than as everyday domestic currency. The electrum question remains genuinely unresolved — spectrographic analysis of comparable pieces has yielded inconsistent gold-to-silver ratios, suggesting either deliberate alloying or regional ore variation.
