1 Cash - Xianchun Yuanbao

The Xianchun reign period (1265–1274) belongs to Emperor Duzong of the Southern Song — a dynasty by then reduced to a rump state clinging to the Yangtze delta while Kublai Khan's Mongol forces methodically dismantled what remained of Chinese imperial resistance. Duzong himself was by most historical accounts disengaged from governance, leaving real power to the chancellor Jia Sidao, whose failed military reforms and land-redistribution policies accelerated the dynasty's collapse. The Southern Song fell to the Yuan in 1279.

Cash coinage of this reign is frequently encountered with uneven casting quality, a product of decentralized provincial mints operating under increasing resource pressure during the final decades of Song administration.
