1 Văn - Đại Định Private issue?

Đại Định was the reign title of Lý Anh Tông, who came to the throne as a child of three in 1138 under the regency of Đỗ Anh Vũ. Cash coins of this period circulated alongside a substantial volume of imported Chinese coinage, and the distinction between officially sanctioned imperial issues and privately cast pieces was rarely enforced with consistency under the Lý dynasty. Toda's classification of this piece as a private issue reflects recurring ambiguity in Vietnamese numismatics — the foundry practices and alloy controls that would distinguish state from informal production are simply not well documented for twelfth-century Đại Việt.
