五铢钱始铸于西汉武帝元狩五年(前118年),流通到唐高祖武德四年(621年),历时739年,种类繁多。因史书记载失详、失记者甚多。给后人在收藏研究方面带来许多难处。笔者根据近几十年各地出土发现,对照收藏实物,结合史料,谈谈对五铢钱识别的个人心得。不当之处,请专家指正。五铢钱多达30多种,准确无误地识别实非易事,但亦并非高不可攀。具体办法是先易后难,逐步缩小范围,最后集中力量解决不易识别者这个大难点。要解决此难点,需靠学问、靠经验,而简易的办法,是象识别诸多亲朋好友那样去识别差异微小的五铢钱。 Five baht money began casting in the Western Han Emperor Wu Yuan five years (118 years ago), circulation to the Tang Gaozu Takenori four years (621), which lasted 739 years, a wide variety.
