1 Văn - Thiệu Phong Bình Bảo, regular script, private issue?

Thiệu Phong was the reign era of Trần Dụ Tông, who took the throne as a teenager and ruled through a period of mounting internal decay within the Trần dynasty. His reign coincided with repeated Cham incursions from the south and growing instability at court — not conditions under which careful monetary oversight flourished. The "private issue" attribution in Toda reflects longstanding uncertainty about whether this piece was struck under direct royal authority or produced by unofficial workshops operating in the dynasty's name, a distinction that matters considerably for provenance but remains unresolved in the literature.
