西海里（서해리）Seohae-ri

发现时间：1957年4月。西海里第三农业合作社制作苗床时发现，遗物集中在约150厘米范围内，地面确认有炉渣或无柄凿状物（厚约2毫米宽约1毫米），推断为包装材料；鸭绿江上游三角地带平地遗址，除钱币外未确认其他遗物。

Discovery year: April 1957. Found by the No. 3 agricultural cooperative of Seohae-ri while preparing a seedbed; the finds were concentrated within an area roughly 150 cm across. Slag-like or tang-less chisel-shaped fragments (about 2 mm thick, 1 mm wide) were noted on the surface and are thought to be packaging material. The site lies on flat land in the delta of the upper Yalu River; no finds other than the coins were identified.
