Some of these coins had precise markings ('常是' [pronounced "joze"], which was the heredity name of a refiner, and '寳' {pronounced "ho"], meaning "valuable") and the year they were made, while others were inscribed with the image of Daikokuten (Great Black God) on one or both sides, probably to indicate that they were prizes or gifts.
表面には「常是」および「寳」に加えて年代を現す文字極印が打たれ、また片面ないし両面に大黒天像の極印が丁寧に打たれたものが存在し、恩賞および贈答用とされる。
