Most expensive wine that accidentally broken in an auction?

I can't give you a definitive answer to the most expensive wine accidentally broken at an auction. Here's why:

* No Central Database: There isn't a global record-keeping system that tracks all wine auction mishaps.

* Privacy: Auctions are often private events, and information about accidents might not be publicly released.

* Unreported Events: Many smaller accidents may go unreported, especially if the damage is minor or the wine isn't exceptionally valuable.

However, there are some famous instances of expensive wine being damaged at auction:

* Château Lafite Rothschild 1869: In 2009, a bottle of this rare vintage, estimated to be worth over $100,000, was accidentally broken by a bidder during a Sotheby's auction.

* Romanée-Conti: There have been reports of this Burgundy grand cru being damaged at auction, though specific details and value are difficult to confirm.

It's worth noting that:

* Insurance: Most valuable wines at auction are insured, so the financial loss is often covered.

* Collector's Market: While the loss of a rare wine is unfortunate, it's important to remember that the collector's market is constantly changing, and the value of a wine can fluctuate.
