Note:
Barker attributes this coin to the reign of Mạc Hien Tông, Quảng Hòa (廣和) (1540-1546). However, Thierry (2002, CMVS), following Miura Gosen, regards this as a later unofficial issue (see below).

Note:
Thierry notes that seal script was not used for official coins of the Mạc Dynasty. He classifies this coin as a "Private issue (17th - 18th centuries)", and groups it among "Small coins inspired by official Vietnamese issues".
