The value of art is reflected in the market and cannot be referenced. What do collectors say and what is the estimated market price of something? There is a saying called antiques in prosperous times and gold in troubled times. The value of antiques lies in archaeology, scientific research and artistic value. What is the value of modern artworks? Was there any work like this before the Central Committee proposed the Chinese Dream? I think the value of art is given by people who understand art. Therefore, the value of pure works of art is a matter of opinion. You collect because you like it. If you care too much about market value, I advise you not to collect. There are too many collection routines.
