Valuable.
There are fewer porcelain Buddha statues in the Ming Dynasty than Buddha statues made of other materials at the same time, and they are even more difficult to preserve! Therefore, the value has continued to "climb" over the years, ranging from hundreds of thousands to millions. It's very valuable.
The ceramic Buddha statues of the Ming Dynasty were mainly on white glaze, and the Dehua kiln in Fujian is the most representative. Most of the white-glazed Buddha statues seen so far are the works of Dehua kiln.
