精品推荐：崇宁通宝

崇宁通宝是北宋徽宗赵佶崇宁年间(1102-1106年)始铸，年号钱。有崇宁通宝、崇宁重宝和崇宁元宝三种。 崇宁通宝当十型，钱文为徽宗亲书，所以又其为御书钱。该钱文书法清秀骨瘦，铁划银钩，是徽宗赵佶瘦金书体存留世间的真实显现。宋徽宗更因铸钱精绝，当时官造成色在96%-96.7%，高于崇宁重宝、崇宁元宝，而与王莽并称“钱法二圣”，是现在青铜钱中价值最高的两种钱币之一。

Chongning Tongbao was first cast in the Chongning period (1102-1106) of Zhao You, Huizong in the Northern Song Dynasty. There are three kinds of treasures: Chongning Tongbao, Chongning Chongbao and Chongning Yuanbao. Chongning Tongbao Dang type 10, Qian Wen is Huizong's relative book, so it is imperial book money. The Qian's handwriting is delicate and thin, with a silver hook drawn by iron. It is the true manifestation of Zhao You's thin gold style of Huizong that remains in the world. Huizong of Song Dynasty had excellent coinage. At that time, the official color was 96%-96.7%. It was higher than Chongning Chongbao and Chongning Yuanbao. He was also called "the two saints of money law" with Wang Mang, and was one of the two most valuable coins in bronze coins.

该钱体厚重，青铜质，锈色古旧，开门的老生坑。之所以谓之大字版，是因此品钱文四字饱满，寄廓接缘。“宝、宁”二字冠点长且向左倾；长点“崇”，斜丁“宁”，高走“通”等，与被公认的各谱均载的大字“崇宁通宝”雷同。除钱径略小外，轮廓宽窄、 穿孔大小、成色亦基本一致。

The money is thick, bronze, rusty and old, open the old pit. The reason why it is called the big-character version is that the four characters of Qian Wen are full and close to each other. "Bao, Ning" has a long and left-leaning crown, while "Chong", "Ning" and "Tong" are the same as "Chong Ning Tong Bao", which is widely recognized as the word of "Chong Ning Tong Bao". In addition to a slightly smaller diameter of money, the outline is narrow, the size of perforation, and the color is basically the same.

在制炼工艺上，“胆水冶铜”正式成为一种实用性生产铜的方法。崇宁二年(公元1103年)时，全国胆铜总产量达到了1874427斤，约占当时铜产量的12%。而在赵宋王朝偏安江南以后，所领江南14州的铜产量锐减，而乾道年间胆铜产量仍有21万斤，竟占到南宋当年铜总产量的80%。所以宋代的人对胆铜生产非常重视，南宋人张甲曾专门写了一部书《浸铜要略》，记载了当时胆铜的生产情况。关于浸取胆铜的具体操作，《宋史·食货志》有记载：把生铁打成薄片，排放在贮有胆水的槽中，浸渍几天，然后刮取析出的泥状铜(称作“赤煤”)，入炼炉化炼。当时的效益，大约每用铁二斤四两可得铜一斤，技术水平是相当高的。此外，那时还有利用胆土煎铜的“淋铜法”，基本原理与“胆水法”是相同的，此法“工多利少”，但“其土无穷，若比之矿铜，其利已厚”，所以也被普遍利用过。

In the smelting process, "bile water smelting copper" has formally become a practical method of copper production. In the second year of Chongning (1103 A.D.), the total output of bile copper reached 1874427 kg, accounting for about 12% of the copper output at that time. After the Song Dynasty, the copper output of 14 states in the south of the Yangtze River declined sharply, while the output of bile copper in Qiandao was still 210,000 jin, which accounted for 80% of the total copper output in the Southern Song Dynasty. So people in the Song Dynasty attached great importance to the production of gallbladder copper. Zhang Jia of the Southern Song Dynasty wrote a Book "Brief Introduction to Copper Immersion", which recorded the production of gallbladder copper at that time. As for the specific operation of leaching gallbladder copper, Song Shi Die Goods Records recorded that pig iron was sliced and discharged into a tank containing gallbladder water, soaked for several days, and then scraped out muddy copper (called "red coal") and smelted in a smelting furnace. At that time, about one kilogram of copper could be obtained for every two kilograms of iron, and the technical level was quite high. In addition, at that time, there was also the "leaching copper method" of decocting copper with gallbladder earth. The basic principle was the same as the "gallbladder water method". This method was "more work and less profit", but "its soil is infinite, if it is thicker than copper ore, its benefit is already thick", so it was also widely used.

宋代作为中华民族历史上冶炼制作工艺高度发达时期，钱币铸造工艺精湛。其中，崇宁通宝为最！崇宁通宝存世量稀少。据我们目前所能见者，有泉家评：“范各一体，体各一态，或如美女簪花，自然窈窕，或如天孙织锦，文采斑斓。”无论是钱文书法的考究，还是铸造的精整都为上乘，堪称为艺术品。

The Song Dynasty was a highly developed period of smelting and manufacturing technology in the history of the Chinese nation, with exquisite coin casting technology. Among them, Chongning Tongbao is the most!Chongning Tongbao is rare in the world. According to what we can see at present, Quanjia commented, "Fan is one and all in one, or beautiful hairpin flowers, natural graceful, or like Tiansun Brocade, with beautiful literary style." Whether it is the exquisite writing of money or the fineness of casting, it is a fine work of art.
