补充资料：圆孔圆钱
中国战国时通行于三晋和周的一种中有圆孔的圆形铜币。此钱一般无内外郭,背为平背。钱上有"共"、"垣"、"蔺"、"离石"、"襄阴"、"漆垣"、"安臧"、"东周"、"西周"、"共屯赤金"、"半睘"等文字,大多为地名或国名，如共、垣属魏，蔺、离石属赵，安臧属周，东周、西周为国名。这类圆钱大小不一，大致可分为大小两类。大钱直径 3.5～4厘米，重约 10～18克；小钱直径 2.5厘米左右。大钱中的"漆垣"则标明"一"，可见小钱当为半。"半睘"属小钱，钱文"半睘"即指半小圆钱而言。安臧钱的书体和安臧空首布上的"安臧" 2字相似,表明两种钱铸造年代相近,似应在战国早期或中期。三晋圆钱品种较多，其中有些当和周钱同时，有的可能较晚。传世品中还有一种文曰"重一两十二珠"(或释"珠重一两，十二")的圆孔钱，前人或以为是秦钱，因为此钱的资料太少，情况很难弄清楚。
战国时三晋的各种圆钱，铸造较少，故流传至今的实物不多，较常见的仅共、垣两种，山西省闻喜、侯马和河南省的辉县、洛阳等地曾有出土。周钱中唯安臧钱近年有出土品。
