According to common sense, Xuantong's three-year Daqing silver coin should be silver, but there are exceptions to everything. If you come across an excellent sample made of copper or lead, you think it is a fake, which is a big mistake, because it may be an extremely precious and rare trial cast copper sample or lead sample, and its value is 100 times that of this silver coin. An ordinary Xuantong three-year Daqing silver coin can fetch tens of thousands of yuan in the auction company, while an ordinary Xuantong three-year Daqing silver coin can fetch more than one million yuan in the auction company, which is very good. This is not a myth, but a fact, but outsiders simply don't understand its value. Ok, I have revealed all the secrets of the industry to you, please accept it!
