Chongning Tongbao was one of the most important coins in Huizong period of Song Dynasty, so it was very difficult to imitate it. At present, there are two ways of counterfeiting in the market. One is to alter it, that is, to change it into precious coins with ordinary coins. The other is counterfeiting. If we compare counterfeit coins with real coins, it is not difficult to find that, first of all, from the point of view of words, there is no strength and strength of the thin body, nor the atmosphere of imperial script. Another is to look at its casting, the real coin miner exquisite, in the magnifying glass is also difficult to see trachoma, and the quality of the counterfeit coin is rough, no texture, that is, without the magnifying glass can also see its trachoma.

Chongning Tongbao is extremely rare in the world. According to what we can see at present, Quanjia commented, "Fan is one and all in one, or beautiful hairpin flowers, natural graceful, or like Tiansun Brocade, with beautiful literary style." Whether it is the exquisite calligraphy of money or the fineness of casting, it is excellent and can be called a work of art. Hence, the Quanjia of later generations called the coins minted in the three dynasties of Han Wang Mang, Song Huizong and Jin Zhangzong as "three unique ancient springs".
