1 Masa

The masa was a unit of weight before it was ever a coin — rooted in the Sanskrit māṣa, a seed-weight measure used across South and Southeast Asian trade networks for centuries before any mint formalized it in silver. Whether the pieces attributed to this broad classification were struck by a single authority or represent accumulated issues from competing port polities along the Malay Peninsula and Sumatra remains genuinely contested among specialists.

The HCM reference range covers a span of five centuries, which alone signals how much remains unresolved about attribution and sequencing.
