古代使用铜钱不论大小，当中都有一个四方形孔眼，为什么有方孔？难道仅仅为了串钱方便吗？不是。铜钱方孔，主要是由于当时制造铜钱的方法决定的。
开始是熔铜铸钱，为此铜钱的轮廓总不整齐。为了使铜钱的周边齐整，必须用锉刀修锉。但是一枚一枚铜钱修锉是很费工的，所以就在铜钱当中开一个孔，将一百来个铜钱穿在一根棍上，一次搓成。
但是如果当中的孔是圆的，铜钱就会来回转动不好锉。因此工匠们就把当中空做成方形，穿进一个方棍修锉，这样铜钱就不会转动了，这就是古代方孔铜钱来历。
另外有一说铜钱做成四方形孔眼是基于古代人天圆地方的理念。
乾隆通宝
正面钱币外圆内方，古人认为天是圆的地是方的，所以用上好的玉制作成玉璧用来祭天，后期发展成流通货币，可以用玉璧来购买物品，古钱币也正是由此而来，最早的古币是外圆内圆与玉璧无异，后期由于打磨容易发生转动，为了更高效的制作钱币，就发展出外圆内方的钱币，也方便固定，大大提高了制作效率，古钱币就由此而来，所以古钱币不只是一种流通货币，更是一种可以用来辟邪去恶的法器，道教就有用乾隆通宝制作的金钱剑，用来做法驱邪，圆为乾方为坤，乾坤之间四字直读‘乾隆通宝‘’表面部分产生包浆，古韵十足，开门见老师不可多得的收藏级钱币。
乾隆通宝为五帝币之一，法力很强，又因其乾谐音，‘钱’，故有钱运兴隆之意，历来为古币收藏者所喜爱，更称之为皇帝的钱币，是用乾隆皇上命名的钱币，而乾隆皇帝是历史上最长寿的皇帝，活了八十九岁，收藏此币也有长寿之寓意，多种寓意让此币成为明星钱币，为钱币收藏之经典。
