How much is Yue Fei's original work worth?

Whether Yue Fei has any works handed down from ancient times is still controversial. Many experts are still skeptical about several original calligraphy works of Yue Fei, and think that they are works copied by later generations. However, from 2005 to 2009, Zhao Mengfu and Yue Fei's contemporary paintings and calligraphy were sold at Sotheby's for 700-150,000. As a national hero, if his works are authentic, his artistic value and spiritual value will definitely be higher than that of Zhao Mengfu. Counting the inflation rate in recent years, the transaction price is estimated to be around 50 million to 60 million.
