有关夹锡钱的问题,近几年《陕西金融·钱币专辑》和《钱币研究》都刊登过不少专家和爱好者的论文,笔者读后受益非浅。但宋代夹锡钱的研究众说纷纭,各说各理。《陕西金融·钱币研究》95年第二期,登有山西杨宏伟先先《品泉说夹锡》一文,文中结论说:“这种锡包铜(或锡包铁)的钱,就应是夹锡钱。”笔者对此不敢苟同。 我认为要弄清什么是夹锡钱这个问题,必须先对我国古代冶金技术有一定的了解,也就是对青铜器知识要有一定的了解。青铜器的合金成份约为铜占84.77％、锡占11.64％、铅占2.97％,冶炼温度在1000℃以上。青铜的冶炼和铸造技术我国发展很早,商代已相当发达,曾在殷墟发现规模宏大的青铜器作坊遗迹,在郑州又发现商代前期的炼铜遗址。从我国古代铜镜的合金配合成份及铸造也可以看出一定的问题(因为铜镜与钱币铸造原理相近),《考工记》中记载了古代铸造青铜器有六种合金配合成份的方式。其中对铸造青铜镜的合金配合成份就有“金锡半”的明文记载。根据有关部门对战国铜镜进行化学成份分析所得出的数据表明,战国铜镜的铜、锡比例为3:1,但战国铜镜铜、锡、铅比例不是固定的,特别是含铅量,相差比较悬殊,最高达到16.9％,最低的为5％,汉代铜镜及汉以后的铜
The problem of folder tin money, in recent years, “Shaanxi financial coin album” and “coin studies” have published many experts and enthusiasts papers, the author benefited from reading. However, there are different opinions on the study of money-holding money in the Song Dynasty. In the second issue of “The Study of Finance and Money in Shaanxi” No. 95 in 1995, Yang Hongwei first wrote the article entitled “Pinchuang Pinchuang”, concluding: “The money of this tin-clad copper (or tin-coated iron) should be Folder tin money. ”I disagree with this. I think to understand what is the problem of clip-tin money, we must first understand the ancient metallurgy technology in our country, that is to say, we must have some knowledge of the bronzeware. Bronze alloy composition is about 84.77% copper, tin accounted for 11.64%, lead accounted for 2.97%, smelting temperature above 1000 ℃. Bronze smelting and casting technology developed very early in our country, Shang Dynasty has been quite developed, Yin Ruins found in the large-scale bronze workshop relics, found in Zhengzhou Shang Dynasty copper smelting ruins. From the ancient bronze mirror alloy composition and casting can also be seen some of the problems (because the bronze mirror and coin casting principle is similar), “Kao Gong Ji” records the ancient bronze casting with six alloy with the ingredients of the way. One of the alloy bronze mirror casting ingredients have a “golden tin half” in clear text. According to the relevant departments of the Warring States mirror chemical composition analysis of the data obtained show that the Warring States bronze mirror copper and tin ratio of 3: 1, but the Warring States bronze mirror copper, tin, lead ratio is not fixed, especially the amount of lead, The difference is relatively poor, up to 16.9%, the lowest is 5%, Han bronze mirror and after the copper
