Quinarius - Shamnar Yuhan'im Raidan

The Himyarite kingdom of southern Arabia developed a coinage tradition that borrowed heavily from South Arabian predecessors while gradually asserting its own dynastic identity. Shamnar Yuhan'im was among the rulers who consolidated Himyarite dominance over rival tribes in the Yemeni highlands during the early second century, a period of active competition with the Sabaean kingdom before Himyar's eventual absorption of it.

The high silver fineness is characteristic of Himyarite issues before monetary debasement accelerated later in the dynasty's history.
