30 Ratti - Harikela Kingdom

The Harikela kingdom occupied the coastal Bengal region roughly corresponding to modern Chittagong and Comilla, and its silver coinage is among the thinnest and most broadly spread of any medieval South Asian issue — a direct consequence of being struck to a very low module weight across an exceptionally wide flan. These coins passed through a trading network heavily tied to the Bay of Bengal's port economy, and examples turn up across a remarkable geographic range, from mainland Bengal to Arakan.

The Mitchell East Asia reference remains the primary catalogue authority for this series, and attribution within it is frequently contested among specialists due to inconsistent die relationships across surviving specimens.
