3 Khumsiyyah

Tarim, a city in the Hadhramaut valley of what is now Yemen, operated as a semi-autonomous sheikhdom whose local copper coinage served trade networks stretching into the Indian Ocean world. The Khumsiyyah denomination — literally referencing a fifth — reflects the fractional accounting systems used across the Arabian Peninsula and the Swahili coast, where Hadhramaut merchants were deeply embedded.

KM#206 is among the more obscure provincial Arabian issues, and genuine examples are frequently confused with contemporary imitative pieces struck for the same trade circuits.
