1 Cash - Cám Thiệu Nguyên Bảo, regular characters, private issue?

Cám Thiệu is not a recognized reign title in the standard Vietnamese dynastic record, and Toda's attribution of this type to a private or unofficial issue reflects genuine uncertainty about its origin. The 1368–1370 window falls within the reign of Trần Nghệ Tông, a period of severe internal instability in the Trần dynasty — court factionalism, Cham military pressure from the south, and weakening central authority all plausibly created conditions under which unofficial cash production could circulate without suppression.

Toda #24 is among the more contested attributions in his Vietnamese series.
