Guangdong Shouzi Yiliang, Shouzi 7,200 cents and Shouzi 7,200 cents are all silver coins that existed in the past. One or two longevity characters are the small ten treasures of Chinese silver coins. Seven cents and two cents are silver coins in circulation. But your money is not real. The back is almost the same as real money, but the front Chinese characters are not the same as Manchu, which is very different from real money. This difference shows that it is not imitation, but fiction. The Chinese characters of real money are the same as Shouzi 12, Shouzi 7- Qian -2 and Shouzi 7- Qian -2. Besides, your Chinese characters are different from real money. For example, the vertical pen in the word "Dong" has a left tick just like the word in this article, and your coin is just a vertical pen. Your money is not only different in strokes, but also far from real money in calligraphy art. However, there are old traces of natural patina and years on your money surface, so it is not a new fake, but something with years.
