Larin - Tahmasp I long variant

The larin — a wire coiled into a tight figure, then folded and stamped — was one of the Persian Gulf's dominant trade currencies for over a century, circulating from the Levant to the Malabar Coast. Tahmasp I's long reign produced considerable variation in these pieces; the "long variant" designation reflects differences in the wire length before folding, which directly affects the final form rather than any change in issuing authority or policy.

Portuguese traders documented larins extensively in 16th-century accounts from Hormuz, where they accepted them as payment alongside their own coinage.
