A coin in the Northern Song tradition but with block-shaped characters. This denomination and the 2-cash with seal script characters were known as Jianyan original treasure. The 3-cash denomination you posted separately is characterised as Jianyan circulating treasure.

Similar sets of coins with varied script were maintained up to the chunxi era. From chunxi 7 (1180), they were succeeded by coins in strictly uniform calligraphy.
