In some countries, such as Australia, auction is a common method for the sale of real estate. Used as an alternative to the private sale/treaty method, where a price is disclosed and offers can be made to purchase the property that price, auctions were traditionally used to sell property that, due to its unique characteristics, was difficult to determine a price for. The law does not require a vendor to disclose their reserve price prior to the auction. During the 1990's and 2000's, auction became the primary method for the sale of real estate in the two largest cities, Melbourne and Sydney. This was largely due to the fact that in a private sale the vendor has disclosed the price that they want, and potential purchasers would attempt to low-ball the price, whereas in an auction purchasers do not know what the vendor wants, and thus need to keep lifting the price until the reserve price is reached.
The Romans also used auctions to liquidate the assets of debtors whose property had been confiscated.[8] For example, Marcus Aurelius sold household furniture to pay off debts, the sales lasting for months.[9] One of the most significant historical auctions occurred in the year 193 A.D. when the entire Roman Empire was put on the auction block by the Praetorian Guard. On 28 March 193, the Praetorian Guard first killed emperor Pertinax, then offered the empire to the highest bidder. Didius Julianus outbid everyone else for the price of 6,250 drachmas per guard,[citation needed] an act that initiated a brief civil war. Didius was then beheaded two months later when Septimius Severus conquered Rome.[8] 

Private sources. In addition to these free government sites, you can use private sites. These sites provide information about federal and local government auctions. Gov-Auctions gives you access to both federal and state auctions. The sites charge a one-time fee of $39.00 for access to their information. Having all auctions on one site can be helpful. If you are launching a serious car search or buy auction cars on a frequent basis, paying to use this site might make financial sense
Local police auctions. If you are interested in local police impound car auctions the best way to find information is to call your local police department. They can provide with the dates and details. Under no circumstances should you call 911 for this information. Look in the local blue pages for the non-emergency number. They are also required to run ads in the local newspaper about 90 days prior to the auction. These are often low key ads in the classified section, so finding them may require some searching. Some police departments put auction information online, so you can also search the Internet
Treasury Bills Auctions are typically held every Tuesday and successful bids are settled on the following Thursday on a T+2 settlement cycle. When the auction date, or the settlement date, or any day in between the auction date and the settlement date falls on a non-business day, the auction takes place on the first business day of the same week and settled on a T+2 basis.

Dutch auction also known as an open descending price auction.[1] In the traditional Dutch auction the auctioneer begins with a high asking price for some quantity of like items; the price is lowered until a participant is willing to accept the auctioneer's price for some quantity of the goods in the lot or until the seller's reserve price is met.[2] If the first bidder does not purchase the entire lot, the auctioneer continues lowering the price until all of the items have been bid for or the reserve price is reached. Items are allocated based on bid order; the highest bidder selects their item(s) first followed by the second highest bidder, etc. In a modification, all of the winning participants pay only the last announced price for the items that they bid on.[1] The Dutch auction is named for its best known example, the Dutch tulip auctions. ("Dutch auction" is also sometimes used to describe online auctions where several identical goods are sold simultaneously to an equal number of high bidders.[19]) In addition to cut flower sales in the Netherlands, Dutch auctions have also been used for perishable commodities such as fish and tobacco.[2] The Dutch auction is not widely used, except in market orders in stock or currency exchanges, which are functionally identical.[1]
As you browse the government auction sites above, you'll notice some link you to additional sites run by private contractors. These contractors have legitimate relationships with the government, but bidder beware: other private companies will try to make their auctions seem like government auctions as a marketing ploy. Always start with the legitimate links provided by the government itself. Good luck!
I wasn't aware that the TSA sold all of the stuff it confiscated! That's cheap goods right there! My mom works for a cruise line, and they don't confiscate stuff, but people do tend to forget all kinds of things they bring on the ship, so every once in a while the company has a big flea market available to employees. I find it funny when my mom comes home with watches and bracelets she wouldn't have otherwise bought.
