What is the value of Cao Shouhuai's calligraphy? Is it collectible?

Can only say that he is a little famous in the local area, and the actual price of his calligraphy works is 300-500 yuan per square meter. Above this price, a group of his students are speculating. Anji County is the hometown of Wu Changshuo in the late Qing Dynasty, so it is the hometown of calligraphy and painting. Now, Anji is full of young people. After all, he is old, and now he is over 90 years old. As a junior, he should respect his old man.
