1 Cash - Hoàng Trần Thông Bảo

Issued under Trần Thánh Tông during one of the most militarily pressured reigns in Vietnamese history — the Mongol invasitions under Kublai Khan were already probing the northern borders by the mid-1270s, and the imperial court was simultaneously managing tribute demands from the Yuan dynasty while maintaining the fiction of full sovereignty. Whether that geopolitical strain affected mint output for this type is unrecorded, but Trần dynasty cash coins of this period survive in notably uneven quality, likely reflecting disrupted production in the lead-up to the first full Mongol invasion of 1284.
