1 Cash - Trị Bình Nguyên Bảo, with reverse rim

Issued under Lý Cao Tông, whose reign was defined less by stable governance than by repeated peasant uprisings and the near-collapse of central Lý authority in the Red River Delta. The Trị Bình era cash were produced during a period when the dynasty's grip on the northern territories was actively contested, making consistent mint output unreliable. The reverse rim variant — cataloged distinctly by Barker — reflects a secondary production run, likely from a different die pairing, and is the less frequently encountered of the two known types.
