In Yuan Datou in the third year of the Republic of China, Yuan Shikai's "signature edition" was very popular among collectors. One is the English signature version of the Italian plate maker cast by Tianjin Mint in the third year of the Republic of China; The other is a signed version of Yuan Shikai's left portrait behind his neck. The above two kinds (five kinds) are sample coins, which have not been officially circulated, so there are not many surviving. At present, the reference prices of several books are1.50,000-30,000 yuan. Some coin friends asked why the really precious coins have not been sold well recently. The author thinks that the main reason is that there are too many imitations made of various materials and means in silver coins, especially high-grade silver coins, accounting for almost more than 90%. Especially in recent years, the "rare" fake silver coins made of real silver by laser phototypesetting are not only common, but also more "real" and "clear" than real coins! People can't tell the truth from the false, which makes many people deceived; In addition, real collectors know that it is a good coin because of limited financial resources, but because of lack of money, they can only look at the coin and sigh, which is also the main reason why precious coins can't sell at a good price. Therefore, the relationship between actual value, "reference price" and sales price is not static. The so-called "sellers" also have some luck. Generally speaking, the price at auction is considerable.
