What is the value of ivory folding fans in Qing Dynasty?

The value of ivory folding fans in Qing Dynasty is still considerable. Because of the protection of the teeth, there are fewer and fewer ivory products, and ivory folding fans are also very rare, and even fewer ivory folding fans in Qing Dynasty. The specific price depends on the preservation and appearance. At that time, I saw such a fan in Suzhou Lingyun Fan factory, and the price was about 10,000 yuan.
