What is the most expensive tea pot ever sold?

There isn't a definitive answer to the "most expensive teapot ever sold" because:

* Price fluctuations: Prices of antiques and rare items can vary greatly depending on the market, auction house, and specific buyer.

* Private sales: Many high-value items are sold privately, without public records of the sale price.

However, some contenders for the title of the most expensive teapot include:

* The "Warring States Period" teapot: This bronze teapot from the Warring States period in China (475–221 BC) was auctioned in 2010 for an estimated $1 million USD.

* The "Yuan Dynasty" teapot: Another Chinese teapot, this one from the Yuan Dynasty (1271–1368), was sold at auction in 2015 for an estimated $750,000 USD.

It's important to note that these are just examples, and there could be even more expensive teapots out there that have been sold privately or haven't been documented.
