Ancient coins It is also called spring, cloth, silk, Kong Fangxiong, etc. Now it has become a hot spot for new collection investment, and many ancient coins have performed well at auctions. Collecting and appreciating ancient coins requires mastering knowledge about currency history, numismatics, archaeology, epigraphy, cultural relics, ancient Chinese, etc. Some coins look ordinary in appearance, but are actually treasures. Experts It is easy to obtain treasures from sellers who do not understand the value of ancient coins. Here are some basics.
1. Ancient coins were cast, and the shape of the mold was like a big tree. This method of casting coins is called "money tree". The larger the quantity, the lower the value of the coin. Because the molds are carved by hand, there will inevitably be omissions. If the version is missing from the inspection and trial minting, it will become a treasure.
2. Contemporary numismatists divide ancient coins into ten grades based on the rarity of various coins and the current coin collection market conditions, namely: first-level treasures, second-level treasures Column, level three
Level three is rare, level four is rare, level five is rare, level six is ??rare, level seven is rare, level eight is rare, level nine is more, and level ten is common.
3. The appearance of coins is summarized into five evaluation criteria: beautiful, near-beautiful, high-end, near-high and medium. 1. Beautiful means that the outline of the front and back of the money is complete and the money's text is clear; 2. Near beauty means that the outline of the front and back of the money has slight deviations or tiny cracks, or the paper has tiny leaks. At the same time, small adhesion or chaos caused by the wear and tear of casting and use are also near American coins; 3 above refers to defects and leaks that can be seen by the naked eye on the front and back of the money. However, it did not damage Qian Wen's writing; 4 near and above means that the defects, cracks, and leaks on the front and back of the coin are more obvious, and have caused one or two broken pens in Qian's Wen Wen
. 5 has no great collection value.
4. There are many types of coins
1. Shell coins, also called tooth shells, are made from polished and perforated saltwater shells in tropical seawater. They are generally milky white and basically the same size and weight. Shell coins began in the Yin Dynasty, when shells were a valuable commodity. The use of shell coins dates back to the Xia, Shang and Zhou dynasties and plays an important role in the history of currency in my country. There are roughly six types of coin shells: currency shells, pseudo-date shells, Lingwei torreya shells, Awen Shou shells, large
small hole shells, and back-milled shells.
2. Qin Banliang is also called Liangqian. It was cast by Qin Shihuang and was the only currency popular in the country at that time. Qin Banliang is round on the outside and square on the inside. The money and text are high and sharp, simple and honest.
3. Wanqian, also known as Wanjin, Wanfa, and Huanqian, is a copper round currency that appeared in the middle of the Warring States Period. This coin is simple to make and easy to carry, and is superior to cloth coins. Round coins eventually replaced cloth coins.
There are two kinds of round holes and square holes in the middle of the round coins. Those with round round holes have no burrs; those with round square holes have burrs on the periphery. Its weight is roughly around 12 grams.
4. Liuquan belongs to the best coins of Wang Mang of the Western Han Dynasty and is valued by collectors. The six springs are: the small spring is straight, the small spring is ten, the young spring is twenty, the middle spring is thirty, the strong spring is forty, and the large spring is fifty.
Today, Zhuangquan and Zhongquan are rare in existence, and the complete set is priceless.
5. The five baht can be divided into the five baht of the Western Han Dynasty and the five baht of the Eastern Han Dynasty, among which the five baht of the Eastern Han Dynasty is more famous. This coin was first minted in the fifth year of Yuanshou, Emperor Wu of the Han Dynasty. It has a round body with a square hole, a narrow outer outline, a diameter of 2.5 cm, and a weight of 3.4-3.5 grams. The five-baht coin is lighter and more delicate than the Qin half-liang coin. However, it takes a long time to circulate and the quantity is extremely large, so it is not valuable.
6. Cloth coins were popular during the Warring States Period. The inscriptions on them were more complex, with more than 100 types ranging from one to four characters. Early cloth coins had a handle for holding the handle, such as Kongshou, Yibu, round-footed cloth, flat-footed cloth, pointed-footed cloth, three-hole cloth, etc., but the inscriptions on the faces were not the same. So there is no distinction between versions. Among them, the three-hole shape is extremely unique, with a round head, round shoulders, and round feet. The cloth head and two feet each have a hole, so it is called three-hole cloth. Moreover, there are many characters on it describing the place names of Zhao State. Later, cloth coins were expanded to Qin, Zhou, Jin, Song, Lu, Yan and other countries.
7. The golden wrong knife is also called the "wrong knife". Wang Mang minted high-face value antique knife coins in the second year of his residence. The body is shaped like a knife, with a large coin attached to it. It is made of bronze. The blade is cast with three seal characters "平五千", and the ring is inlaid with yellow gold with two seal characters "一刀", indicating that a gold knife can be used as a sword. Five thousand dollars for it.
8. Money making, copper coins made in the Ming and Qing dynasties. Because the form, text, weight, and quality are all customized, it is called making money.
9. Yuanbao. The earliest use of the term "Yuanbao" was in the first year of Emperor Qianyuan of Tang Su Zhongzong. In the Yuan Dynasty, ingots began to circulate in the form of silver ingots, usually with the name of the silversmith at the time and place on them.
10. Knife coins evolved from the sharpening of fishing and hunting tools during the Spring and Autumn Period. It usually consists of three parts: a long and narrow arc-shaped blade, a handle with a groove, and a ring at the end of the handle. It can be divided into needle-headed knives, pointed-headed knives, truncation-headed knives, round-headed knives and flat-headed knives. Qi State is the main country that uses sword coins. The sword coins of Qi State are thick and exquisite, and the writing style on the surface is elegant. The sword coins of Yan State are thin in shape, with a wide blade body and complex inscriptions.
There is a word "ming" on the face, so it is called Ming Dao. The sword coins of Zhao State have straight blades and round heads. Today they are often called straight knives and round-headed knives. There are many fakes.
11. Kaiyuan Tongbao, the palace reward money made by Emperor Gaozu Li Yuan of the Tang Dynasty after he abolished the five baht, weighed one tael. The one-liang and ten-coin system in our country's currency system originated from this time. The four characters "Kaiyuan Tongbao" in official script on the front were written by Ouyang Xun, a calligrapher in the early Tang Dynasty. The font is straight and powerful. The production outline is deep and exquisite, and it is very precious. The emergence of Kaiyuan money announced the end of the two currencies, half liang
and five baht, which had been in circulation for more than 800 years since the Qin Dynasty. The word "Tongbao" has been used by successive dynasties since then.
12. Dual money, also known as "dual product" and "pair money", refers to the same kind of money with exactly the same inscription, size, internal and external outline, thickness and copper quality, but using different The calligraphy style, but the glyphs and gestures still match each other and can become paired coins, also called "hehe coins". Money exchange began in the Southern Tang Dynasty and flourished in the Northern Song Dynasty. The "Kaiyuan Tongbao" cast in the Southern Tang Dynasty, with seal script and official script in pairs, was the first to coin money
. In addition, Northern Song Dynasty Tiansheng, Mingdao, Yuanfeng, Xining, Zhenghe, Chonghe, Xuanhe and other coins can be matched.
13. There are three coins of copper, silver and gold. Liu Guangshi made the trust money in the early Southern Song Dynasty to recruit surrender and rebels. Qian's text is read in a convolutional manner, with the word "Shi" and an inscription on the back. Because it is not a currency in circulation,
it is rarely handed down from generation to generation. It is one of the world's rarest coins.
5. The older the collection is, the higher its value may not be. For example, the price of the Han five-baht coin today is only 2 to 5 yuan, while the price of the Ming Dynasty coin is generally higher than the Han five-baht coin. For example, the Ming Dynasty "Hongzhi Tongbao" and "Xuande Tongbao" are priced at More than 10 yuan. Another example is the "Jingkang Tongbao" Dazhenquan product of the Song Dynasty, which costs hundreds to thousands of yuan each, and the "Xiwang Shanggong" Dazhenquan product made by Zhang Xianzhong after he occupied Chengdu in the late Ming Dynasty. , today’s price has reached 25,000 yuan. Don't try to collect all the coins made by a dynasty. For example, although the price of the five baht in the Han Dynasty is low, in the more than 300 years of the Han Dynasty, there were 272 types of coins, most of which have been lost. No matter how much money you have, you can't buy them all. There were only 97 years before and after the Yuan Dynasty, but there were 128 different types of coins made, of which four types of coins have no physical remains.

200 small cloths, 300 small cloths, 400 preface cloths, 500 poor cloths, 600 medium cloths, 700 strong cloths, 800 second cloths, and The cloth is nine hundred, and the big cloth is yellow thousand. Nowadays, among the ten cloths, the large Huangqian cloth is more common, and the other nine cloths are all treasures.

Most of the coins have a gold content of more than 96, some as high as 99. Most of the coins are cast and pressed with "Ying Ai", There are small square stamps with the words "Chen Ai", "Shaoyou", "Ke Ai", "Shou Chun" and so on, so it is also called "Yinzijin", "Cake Gold" or "Jinai".

The bronze coin has a diameter of 3.9 cm, a perforation of 0.7 cm, and a weight of 16 grams. Because it has the country name "Qing" on both sides of the character "Xian", it is rare among the Kongfangyuan coins of all dynasties in my country. Ma Dingxiang, a large collector, bought one in Suzhou in 1940 and it is now in the Shanghai Museum.
