History of Auctioneering
The most expensive seal sold at auction was sold for $22,000,000 (£17,595,777) and was bought by an anonymous buyer (China) in Paris, France, on 14 December 2016. The seal had once belonged to one of China’s longest serving emperors, Qianlong (1735-1796) of the Qing dynasty, who owned 1,800 of them. According to the auction house, the seal was acquired by a French naval doctor during a trip to China in the 19th century, after which it remained in his family.
