| Reverse description | A sinuous imperial five-clawed dragon rendered in high relief occupies the central field, depicted in dynamic profile with finely detailed scales, clawed feet, and flowing whiskers, surrounded by stylized ruyi cloud motifs in the field. At the lower portion of the field, two Chữ Hán characters 五十 (meaning 'fifty', indicating the denomination in phan or relating to the weight standard) are inscribed beneath the dragon's coiling tail. The entire reverse design is enclosed within a raised beaded border matching that of the obverse, consistent with Nguyễn imperial gold coinage conventions. |

| Additional information |
Minh Mạng's reign saw an aggressive centralization of the Vietnamese state, including a formalized bullion coinage system administered directly through the Bộ Hộ — the Board of Revenue — rather than through any commercial mint structure. The 7 tiền weight standard reflects a deliberate indigenous denomination system resisting Chinese metric norms, even as the dynasty drew heavily on Qing administrative models in nearly every other department of governance.
1834 falls within Minh Mạng's intensive southern administrative reforms, the same year he abolished the last vestiges of Gia Long-era regional autonomy in Cochinchina.
