2. Precious metal coins will be bruised when they fall on the ground or touch hard objects, while ancient coins are mostly rusted and may be broken when they fall on the ground. Excessive force can also cause fracture and breakage, so be especially careful about this ancient money with serious corrosion.
3. The surface of ancient coins will generally form protective rust. This kind of protective rust is also called old rust. Rust is hard, green, blue and red. It can protect itself and cannot be destroyed.
4. Qian Wen produced by corrosion can be soaked in strong acids such as edible vinegar and sulfuric acid. When soaking, turn it over at any time to observe that enough is enough, then wash it with water and a soft brush and dry it. Under normal circumstances, it is best not to use physical means to remove rust from ancient coins, otherwise even if they are cleaned, their appearance will be destroyed. Iron coins are easier to oxidize than copper coins, so we should pay more attention to protect the rust on the surface of iron coins, including the ancient colors handed down from generation to generation, otherwise it will only promote their corrosion and get the opposite effect.
5. Gold and silver coins often darken due to long-term oxidation, which affects the appreciation. You can soak them in a small amount of special cleaning solution and then rinse them with clean water.
6. Harmful rust will make money rot quickly and be contagious. Harmful rust is powdery, and coins with harmful rust should be isolated immediately.
7. The collection of coins should be kept by age and category, because different textures have different requirements for temperature and humidity. It can be classified by drawer-type cashboxes, or stored separately by different coin books or plate-type coin boxes. Dry it before entering Tibet to avoid being touched by sweaty hands. Coin cabinets, boxes and books should be kept in a dry and dark place to avoid rusting due to moisture. Paper money should also be prevented from pollution such as oil pollution, and attention should be paid to mildew and moth prevention. In summer, especially after the rainy season in the south, you should see the sun at least once a year.
8. As for the baby, the money should be stored separately to avoid being mixed with ordinary products. The difference between some treasures and ordinary products is only subtle. Special brocade box, velvet box or mahogany box frame can be made, and celebrity inscriptions are added to make it more elegant and luxurious.
Tianxi Bao Tong was cast in the Jubilee Period of North Song Zhenzong (A.D.1017-1021), and Qian Wen read it in regular script.
The market price is generally within 100 yuan.
Zheng He was cast in Zheng He's period in Song Dynasty. Xiaoping, Zheer, and Li Cheng were right. This model has many formats. Iron money has "Zheng He Yuan Bao" as the imperial book of San Qian and Qian Wen. Imperial books and copper coins in Zheng He Chong Bao are very rare.
Chongning Bao Tong was cast in the Chongning period in Song Huizong (A.D.1102-1106). Song Huizong has no political achievements, but his calligraphy is very good. His "thin golden body" is known as "iron attracting silver hook" After he ascended the throne, he wrote Qian Wen's works such as Shengsong Yuanbao, Chongning Bao Tong, Daguan Bao Tong, Zhenghe Bao Tong, etc. This kind of money is called "Imperial Book Money". Among these "imperial grain money", the one who worships Ning is the most beautiful.
The Grand View of Currency in the Northern Song Dynasty is a treasure house, written by Hui Zong of Qian Wen. Song dynasty is different from dynasty. Every time you change the number of a year, you start casting new coins. If the year number and Bowen are important, you will invest in money other than the year number. In the past hundred years in Song San, the main way is to fold two coins into small squares. During this period, a large amount of money also circulated, and the outline and size of coins also had certain standards. Therefore, there are many versions of Song and Qian, which are rare in past dynasties. In addition to the four characters of truth, grass, official and seal, Qian Wen also has a "jade and silver hook" with a thin gold body of Huizong in the Northern Song Dynasty.
"The northern song dynasty emperor worship view, iron painting has a silver hook. I heard that there were few copper goods in Shuzhong, so I let Juetie buy Wangshan! " This poem conveys the vivid thin gold body of Huizong in the Northern Song Dynasty. Hui Zong inherited the throne in his early years and admired the art of calligraphy and painting, but he was not good at governing the country. He wrote a book about Qian Wen himself, such as Chongning Bao Tong and Xuanhe Bao Tong. Qian Qian's imperial script is exquisite in writing and superb in casting technology, ranking first in all dynasties.
The picture shows the imperial book money "Daguan Bao Tong" folded into two yuan. The coins are symmetrical and regular, and the copper color is slightly dark. Qian Wen's "Grand View Bao Tong" is exquisite in font and full of charm. The word "Tong" is a square-headed tong in the Song Dynasty (the word "Yong" is written in a square). There is no inscription on the back. Bao Tong in Daguan can be divided into copper coins and iron coins. In the Northern Song Dynasty, due to frequent wars, excessive casting by officials and the rise of private thieves, there was a shortage of copper products. So the government opened cast iron money. Imperial book iron money includes "Chongning Bao Tong" with a discount of two yuan, "Daguan Bao Tong" with a discount of two yuan, and Xiao Pingqian's running script. Royal copper coin "Chongning Bao Tong" has Xiaoping and 10% discount. There are many ten times editions, and Huizong personally guides craftsmen to elaborate them. "Daguan Bao Tong" has many copper goods, including Xiaoping, discount 2, discount 3, discount 5, discount 10 and extra large money. Among them, Qian Qian's 10% discount is the best, and some versions of Xiao Ping Qian are also great. At present, the super-large copper "Daguan Bao Tong" is mostly handed down from ancient times and rarely unearthed. However, the more traditional view is that in Hui Zong's imperial books, money is the most important, and money for grand view is the second. As a slender Qian Wen, Song Yu's calligraphy and money are far from the aesthetic intention of Xin Mang and Qian Wen.
The market price of imperial book money varies according to the version of the coin. "Daguan Bao Tong" is worth about 20,000 RMB, which is about 70 yuan RMB, while the extra-large Daguan Bao Tong is worth 20,000 RMB. The diameter of money in the Western Grand View is 3.5 cm, and the price is about RMB 1 000. The cheapest is Kuanguo Daguan Coin, and the market price is RMB 5 yuan. In Song Dynasty, coins were minted frequently, and there were many versions of coins, so special attention should be paid to the collection. It is also worth noting that some coins in the Northern Song Dynasty began to recast characters. The inscription on the back begins with the words "Guo and Fang". In the meantime, the word "Shaanxi" was cast on the back of the calligraphy money in Yuan Hutong, and the word "Shaanxi" was also cast in Xuanhe Iron Money. Only these, if there are others, can be classified as pseudo-ancient. We must pay special attention to counterfeiters' counterfeit money and cheat with "out-of-box products" and "orphan products".
Shaosheng Yuanbao was cast by Shaosheng in North Song Zhezong.
Three currencies were minted during Song Zhezong's period. In the first year of Yuan You (A.D. 1086), "Yuan You Bao Tong" copper coins and iron coins were cast. There are two kinds of copper coins: Xiaoping and Zheer, and Qian Wen seal in pairs. The word "Shaanxi" is rarely seen in Xiaoping coins. San Qian's iron coins are folded in half, and Qian Wen's seals and lines are paired. Born less than three years (A.D. 1096), Born less ingot and Born less Bao Tong came out one after another. There are two kinds of copper coins: Xiaoping and Fold, and the seal characters are paired. There is also a kind of official script Xiaoping coin, which is rare. Iron money has Xiaoping, 20% discount and 30% discount, all in pairs. There is a copper cast Xiaoping in Bao Tong coins, and Qian Wen uses regular script, with no words on the back. There is only one kind of iron money in Bao Tong, Xiaoping. In addition, there are iron mother money with the word "stone" on the back, which is extremely rare.
Zheng Long Yuanbao was cast in the Southern Song Dynasty (1 156) when Yan Yanliang was renamed Zheng Long, and it was used as the currency of the Jin State at that time.
Kaiyuan Bao Tong was first cast in the fourth year of Tang Wude (AD 62 1), and every ten pieces weighed one or two. It is also pronounced as "opening an ingot". The back of the money is decorated with stars and the moon, and the version is complicated. After the Tang Dynasty, there was still smelting and casting, but the shape was different from that of the Tang Dynasty. In the Tang Dynasty, a small amount of "Kaiyuan Bao Tong" money was also minted, which was a memorial to the opening of the furnace and was also minted by later generations. In addition, there are very few gold, silver and lead castings in Kaiyuan Bao Tong, which are very rare.
