Many unusual items have been listed for sale on the auction website eBay. Some were successfully sold, while other auctions were stopped by eBay because the listing breached their policies.
An auction is usually a process of buying and selling goods or services by offering them up for bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory.

A spectrum auction is a process whereby a government uses an auction system to sell the rights to transmit signals over specific bands of the electromagnetic spectrum and to assign scarce spectrum resources. Depending on the specific auction format used, a spectrum auction can last from a single day to several months from the opening bid to the final winning bid. With a well-designed auction, resources are allocated efficiently to the parties that value them the most, the government securing revenue in the process. Spectrum auctions are a step toward market-based spectrum management and privatization of public airwaves, and are a way for governments to allocate scarce resources.
Auction sniping is the practice, in a timed online auction, of placing a bid likely to exceed the current highest bid as late as possible—usually seconds before the end of the auction—giving other bidders no time to outbid the sniper.

Philadelphia Media Holdings LLC was an American holding company located in Philadelphia, Pennsylvania, United States. Founded by Brian Tierney in 2006, the company owned The Philadelphia Inquirer and Philadelphia Daily News. After The McClatchy Company bought Knight Ridder in 2006, it announced it would sell, among other newspapers, The Philadelphia Inquirer and Philadelphia Daily News. Interested in buying the papers, Brian Tierney assembled a group of Philadelphia businesspeople and investors to make a bid. In May 2006 Philadelphia Media Holdings bought the papers for $515 million plus the assumption of the newspapers' liabilities. Declining circulation and ad revenue for The Inquirer and Daily News caused financial strain, which resulted in the filing for Chapter 11 bankruptcy protection. The company's creditors acquired the newspapers at auction and established a new holding company, Philadelphia Media Network, in 2010.
The T206 Honus Wagner baseball card depicts the Pittsburgh Pirates' Honus Wagner, known as "The Flying Dutchman", a dead-ball era baseball player who is widely considered to be one of the best players of all time. The card was designed and issued by the American Tobacco Company (ATC) from 1909 to 1911 as part of its T206 series. Wagner refused to allow production of his baseball card to continue, either because he did not want children to buy cigarette packs to get his card, or because he wanted more compensation from the ATC. The ATC ended production of the Wagner card, and a total of only 50 to 200 cards were ever distributed to the public. In 1933, the card was first listed at a price value of US$50 in Jefferson Burdick's The American Card Catalog, making it the most expensive baseball card in the world at the time.
