1 Cash - Chunxi Yuanbao, Regular script, Song, with year, iron

Chunxi Yuanbao was produced under Emperor Xiaozong, whose reign saw sustained military pressure from the Jurchen Jin dynasty to the north. Iron cash of this period were minted in significant quantities across Southern Song furnace operations — copper being increasingly reserved for higher-denomination issues and strategic stockpiling. The dated varieties, specifying the regnal year on the reverse, are a Southern Song administrative habit that aids attribution but does not itself imply rarity.

Hartill 17.210 places this squarely in the standard iron series; survivors in collectible condition are harder to find than their original mintage might suggest, iron being far more susceptible to oxide degradation than bronze.
