No bids were placed on the bell from Christopher Columbus’ Santa Maria, which was up for auction Wednesday morning. The bell is more than 500 years old and worth an estimated $2.5 to $5 million, according to the auctioneer’s website. It was set at a minimum starting bid of $650,000.

This bell was part of the Santa Maria back in 1492. Years later, it ended up at the bottom of the ocean off the coast of Portugal, where it stayed for about 400 years until it was discovered in 1994 by a man named Roberto Mazzara.
