First of all, we need to know what a "knife coin" is. In the field of ancient Chinese coins, knife coins are a kind of ancient coins, and their shapes are like knives, hence the name. Knife coins were mainly circulated in China during the Spring and Autumn Period and the Warring States Period, and the "Qi Dao" minted by Qi was the most famous.
When it comes to knife coins worth more than 10 million yuan, it is actually discussing the collection market of ancient coins. In this market, some rare, well-preserved and historic knife coins can really be worth tens of millions. The evaluation of this value is based on many factors: the amount of existence, historical status, preservation status, casting technology and so on. For example, a well-cast and well-preserved Qi broadsword may be worth tens of millions.
However, it should be noted that there is speculation and speculation in the ancient coin market, so the "ten million-value" knife coins are not entirely based on their intrinsic value, but also affected by the relationship between supply and demand in the market. In addition, the identification and evaluation of ancient coins require professional knowledge and experience. Therefore, for ordinary collectors, we should be cautious when dealing with expensive ancient coins.
Generally speaking, there are knife coins worth over 10 million yuan, which represent the ancient history, culture and economic development of China. However, when collecting and investing in ancient coins, we must have professional knowledge and rational judgment to avoid blindly following the trend and causing unnecessary economic losses.
