The expression "auction off" means to sell something to the highest bidder in a public sale. This type of sale is called an auction. Sometimes when people or organizations have things they no longer want or need, they might decide to sell them through an auction. They will announce the sale, and people interested in buying the items can place bids on them. The person who offers the most money for the item will win it. This is called "auctioning off" the item.
