I have an ancient coin with the words "Heaven and Earth are the same" and "Sun and Moon are the same" engraved on the reverse side. Please help me identify the value.

I can tell you for sure that it costs money. Originated in the Western Han Dynasty, it was cast in the late Qing Dynasty and early Republic of China. Its original meaning is mainly divided into two categories: eliminating evil spirits and disturbing disasters and celebrating and praying for blessings. Later, the scope of wealth aversion became wider and wider, such as furnace-opening, warehouse-keeping, gift-giving, reward, blessing, disaster prevention, divination, appreciation, drama, accessories, zodiac and so on. All these have caused boredom with money. Later, it became more and more widely used. According to different uses, it can be roughly divided into commemorative, war-weary, trustworthy, bridging, supportive, playful, auspicious words, idioms, dramas and other categories. Throughout the past dynasties, all kinds of calligraphy and design contents mostly reflected the customs and habits at that time, so money-weariness has great reference value for investigating the politics, folk customs and culture of each dynasty. There are many materials that hate winning money, besides copper, there are also materials such as gold, silver, tin and lead. The emergence and development of money-weariness was closely related to many aspects of society at that time, and most of them reflected people's good wishes for peace and prosperity. Because of the variety of patterns, casting techniques and materials, the level of money is different. In addition, the government has also cast a lot of money for furnace opening, treasury, gifts, awards, blessings, appreciation and so on. Let the categories of spending money be more abundant.

At present, there are many remains of folk money, including many fine works, which are of great reference value to the study of religious history, folk history, art history, ancient architecture history, sports history and printmaking history.
