It was long considered to be the first type of coin produced in Japan. Analyses of several findings of Fuhon-sen (富夲銭) in Asuka have shown that those coins were manufactured from 683.

The Dangojeon () refers to the 5 mun denomination of the (常平通寶) Korean cash coins introduced in February 1883 following the disastrous introduction of the earlier Dangbaekjeon (當百錢) two decades earlier. The Dangojeon had a nominal value (or face value) that was five times higher than that of the regular yeopjeon, but its purchasing power was just twice as high, like the previous series of high denomination Sangpyeong Tongbo cash coins, this would prove to be a major cause of inflation and disrupted the Korean economy.
