What is the value of Chen Yongwu's calligraphy?

Mr. Liu is the original curator of Shanghai Museum and a great calligrapher. He is much better than those so-called famous artists. Keep it!

Don't sell it, it has no real value yet. Now it's hype "tiles" to sell fire.

However: "Ercao's fame is dead, and rivers will not be wasted forever." Those "tiles" will eventually be eliminated by history and future generations

I hope my answer is helpful to you!
