1 Cash - Cảnh Hưng Nội Bảo

Cảnh Hưng was the reign title of Lê Hiển Tông, who ruled for over four decades — the longest reign of any Lê dynasty emperor — yet exercised almost no real power. The Trịnh lords controlled the north absolutely during this period, and coin production reflected their administration rather than any imperial initiative. Multiple cash types were issued under the Cảnh Hưng title across different decades, making precise attribution within the series genuinely difficult without die study.

Barker's subdivision of this type from the broader Cảnh Hưng series rests largely on fabric and casting characteristics rather than textual distinction.
