This site is a place full of surprises! In China, collectors and scholars tend to focus on the circulation area and minting method of coins, and the origin of minting is only described by some expensive (ten times that of ordinary books) and particularly unpopular (few prints, no one reads) academic books. Therefore, in the impression of Chinese collectors, everyone often knows the age, material, craftsmanship, and circulation range of a coin, but the casting origin is ignored, and it is often tacitly assumed that the capital of the country is the place of origin, of course, because these coins are often unearthed in the capital and provincial capitals. Just like your coin, depending on the state, it is a gift money from the Northern Song Dynasty to the Liao Dynasty in northeast China, which must have been unearthed in northeast China or Inner Mongolia.
In particular, the coins of the Northern Song Dynasty, although a thousand years have passed, but this is one of the best economic eras in ancient China, with a large circulation, just like the Han Dynasty, the coins of the Tang Dynasty are still a few yuan. The quality of coins of the Northern Song Dynasty was one of the best in ancient China, even the ancient coins of various dynasties in China combined did not reach the total amount of coins issued in the Northern Song Dynasty, and even in the Yuan Dynasty, Ming Dynasty, and Qing Dynasty, there were many people using it, because the quality was better than that of subsequent dynasties. Now, a 500g Northern Song copper coin is worth no more than 200 yuan, and ten years ago it didn't even exceed 100 yuan.
Although the meaning of ancient Chinese coins is good, "auspicious charm" is notoriously good because the name has never gone out of style. Other coins often have changed over time, and their meaning is not so strong now. In Chinese encyclopedias, auspicious charms and treasures were a token of the couple who wanted to get married in ancient times. The coins of the Northern Song Dynasty are known as the ultimate of Chinese coins, because of the many varieties, cheap prices, the text is often written by the emperor, and the meaning is related to Taoism (the emperors of the Northern Song Dynasty were even canonized saints by Chinese Taoism), which is the best choice for beginner collectors, and many people even collect for a lifetime.
