Lan Xang — the "Kingdom of a Million Elephants" — was one of the largest kingdoms in Southeast Asian history, controlling much of the middle Mekong basin during its peak. These heavy billon pieces functioned as trade currency across a region where silver coinage from neighboring Ayutthaya and Vietnam circulated simultaneously, forcing Lao minters to produce weights that could be reconciled against multiple foreign monetary systems. The broad date range reflects not a single issuing authority but a dynasty cycling through multiple capitals, including the move to Luang Prabang following persistent Burmese military pressure in the late seventeenth century.
