The Southern Song dynasty refers to an era of the Song dynasty after Kaifeng was captured by the Jurchen-led Jin dynasty in 1127. The government of the Song was forced to establish a new capital city at Lin'an which wasn't near any sources of copper so the quality of the cash coins produced under the Southern Song significantly deteriorated compared to the cast copper-alloy cash coins of the Northern Song dynasty. The Southern Song government preferred to invest in their defenses while trying to remain passive towards the Jin dynasty establishing a long peace until the Mongols eventually annexed the Jin before marching down to the Song establishing the Yuan dynasty.

The Yuan dynasty was a Mongol-ruled Chinese dynasty which existed from 1271 to 1368. After the conquest of the Western Xia, Western Liao, and Jin dynasties they allowed for the continuation of locally minted copper currency, as well as allowing for the continued use of previously created and older forms of currency, while they immediately abolished the Jin dynasty's paper money as it suffered heavily from inflation due to the wars with the Mongols. After the conquest of the Song dynasty was completed, the Yuan dynasty started issuing their own copper coins largely based on older Jin dynasty models, though eventually the preferred Yuan currency became the Jiaochao and silver sycees, as coins would eventually fall largely into disuse. Although the Mongols at first preferred to have every banknote backed up by gold and silver, high government expenditures forced the Yuan to create fiat money in order to sustain government spending.
