How to evaluate the value:
At first glance, historical value is rare.
Ancient coins are the physical objects of currency history and the witness of history. Therefore, it is necessary to find out its position in history before collecting it. For example, "Chengdu Jiaozi" and "Ten-text Series Yuanbao Jiaochao" are the earliest banknotes discovered in China so far, which are regarded as priceless by academic circles; Jilin's "Guangping Silver Coin" is considered to be the first machine-made coin in China. The "Cheng 'an Treasure" unearthed in Acheng County, Heilongjiang Province1August, 985 is a rare "one-half-white silver coin" product in China. Coins made in short-lived dynasties or peasant uprisings are rare treasures because of their short circulation time and small circulation.
Second, look at the existing quantity.
Knife coins of Qi, Yan and Zhao, cloth coins of Korea, Wei and Qin, etc. Very old, rarer and more expensive than round currency. There are not many coins in the world, such as the "Deyi Yuanbao" cast after Shi Siming, a rebel in the Tang Dynasty, occupied Luoyang. Later, it was found that the word "Deyi" was unlucky, so it was changed to "Shuntian" and cast "Shuntian Bao Tong". These two kinds of coins are rarely passed down from generation to generation, especially the "Deyi Yuanbao", which is a rare treasure.
Third, look at cultural values.
Some categories handed down from generation to generation are favored mainly because of their high cultural taste and artistic value. For example, coins such as "fire circle" and "cloth circle" in Wang Mang's new dynasty in Han Dynasty used vertical needle seals; "All Bao Tong", a nine-fold seal script cast during Renzong's reign in the Northern Song Dynasty, is the earliest artistic word in China and a masterpiece.
The four products are about 3 meters apart, and the pottery jar containing coins has been damaged by the excavator. According to the analysis of pottery fragments, it should be two large pottery pots and one small pottery pot. A large number of ancient coins are mixed with soil. Ancient coins should be stacked in strings in clay pots. After a simple cleaning of these ancient coins, the local cultural relics bureau found that the front of all ancient coins was "Kaiyuan Bao Tong". Standardized modeling, exquisite production, clear handwriting and beautiful words. Most of them are 24 cm in diameter, except for the words on the front, there is no mark on the front and the moon pattern on the back. In early Tang Dynasty and middle Tang Dou. The complete coin is about 17000 pieces and weighs about 7 1 kg. It is speculated that these coins should have been hidden by the wartime owners for emergency. In the fourth year of Kaiyuan, Bao Tong coins were first minted in Wude, Tang Gaozu. The casting of Kaiyuan Bao Tong Coin marks the end of the five-baht currency in the history of China's currency development and the beginning of Bao Tong's monetary system. The uniqueness of Bao Tong currency lies not in its shape, but in its name, that is, Qian Wen. Qian Wen's content includes "Kaiyuan" and "Bao Tong". The former indicates the beginning of a new era, while the latter indicates the passing of the treasure. From then on, the square hole coins were no longer named by weight, but changed to XXX (mostly coinage year or country name) Bao Tong, Yuanbao, Chongbao and so on. This Qian Wen structure model became the standard of square hole round money in past dynasties, and it has been circulated for more than 1300 years until the early years of the Republic of China. The casting of Kaiyuan Bao Tongqian had a great influence on the China balance method. Kaiyuan money weighs one or two per ten articles, and copper coins weigh one money per article. Since then, China has adopted the decimal system of 120 yuan, while the original Thai baht,? Stop using such units of measurement. In Qian Wen's calligraphy style, Kaiyuan Bao Tongqian also made some innovations. In ancient China, the characters used for coinage were seal script in the pre-Qin period, mostly seal script in the Qin to Sui period, and official script and kai script were the main characters since Kaiyuan Qian. [4] Ganfeng Lishu Dynasty: In the first year of Gao Zonggan's reign, it was sealed and cast, and one was used as Kaiyuan money. The money body is slightly larger than Kaiyuan money, with a diameter of 25cm and a weight of 33-35g. Because of its short casting period and few handed down from generation to generation, it was mostly unearthed in Shaanxi. Most of them are fakes. 4 Price Reference Editor In view of the special background of the issuance of Ganfeng Quanbao, it has been treasured by collectors and can be sold for one yuan during the Republic of China.

No matter whether coins are rare or not, we should try to avoid those coins with vague faces, defective outlines, serious corrosion and poor faces. When collecting ancient coins, we should also pay attention to whether there are signs such as moon patterns and star patterns. The identification of ancient coins is to distinguish the casting age and address through the words on the back and evaluate their rarity. Generally speaking, coins marked with the moon and stars on the back are more collectible than those with smooth back. Among the coins worth collecting, the palace coins refined from gold, silver and copper are precious cultural relics, with small casting quantity and good quality.
Identification of ancient coins: look at bronzes, rust colors, inscriptions on cities, sounds, smells and editions.
