Hello, I found a lot of big-headed oceans and small-headed oceans at home. How much can I sell it for?

The three most popular varieties on the market were cast in the third, ninth and tenth years of the Republic of China, and the prices were basically between 50-60 yuan, belonging to the low-priced potential varieties among the old silver coins. In the eighth year of the Republic of China, the number of "Yuan Datou" was slightly less, and the current market price was about 1.20 yuan, which was favored by many coin collectors. The number of Yuan Datou published in Gansu Province is very rare, and the current transaction price has reached 1.08 million yuan. The most precious and rare variety of "Yuan Datou" is the "signature version" of Yuan Shikai's head in the third year of the Republic of China. Nowadays, the general postal currency card market is hard to find, even in coin auctions. The current valuation of this coin is about 40,000 ~ 60,000 yuan, which is a rare treasure in modern silver coins and has attracted the attention of coin collectors at home and abroad. The price of Yuan Shikai's small silver coins of 20 cents and 10 cents is generally around 15~40 yuan, while the price of Zhongyuan (50 cents) is more expensive, probably one in 300 yuan.
