There will usually be an estimate of what price the lot will fetch. In an ascending open auction it is considered important to get at least a 50-percent increase in the bids from start to finish. To accomplish this, the auctioneer must start the auction by announcing a suggested opening bid (SOB) that is low enough to be immediately accepted by one of the bidders. Once there is an opening bid, there will quickly be several other, higher bids submitted. Experienced auctioneers will often select an SOB that is about 45 percent of the (lowest) estimate. Thus there is a certain margin of safety to ensure that there will indeed be a lively auction with many bids submitted. Several observations indicate that the lower the SOB, the higher the final winning bid. This is due to the increase in the number of bidders attracted by the low SOB.

One way the federal government finances its activities is by the sale of marketable Treasury bills, notes, bonds, Floating Rate Notes (FRNs), and Treasury Inflation-Protected Securities (TIPS) to the public. Marketable securities can be bought, sold or transferred after they are originally issued. Treasury uses an auction process to sell marketable securities and determine their rate, yield, or discount margin. The value of Treasury marketable securities fluctuates with changes in interest rates and market demand. You can participate in an auction and purchase bills, notes, bonds, FRNs, and TIPS directly from the Treasury or you can purchase them through a bank or broker. Marketable securities held in your account can be sold at current market prices through brokers and many financial institutions.

A primary dealer is a firm that buys government securities directly from a government, with the intention of reselling them to others, thus acting as a market maker of government securities. The government may regulate the behavior and number of its primary dealers and impose conditions of entry. Some governments sell their securities only to primary dealers; some sell them to others as well. Governments that use primary dealers include Belgium, Brazil,[1] Canada, China, France, Hong Kong, India, Italy, Japan, Singapore, Spain, the United Kingdom, and the United States.

Clark County Treasurer’s Office trustee property auctions are generally held once a year in the spring, with possibly another one in the fall.  By state law, real properties that have delinquent taxes (including applicable penalties, interest, and costs/fees) remaining at the end of three consecutive fiscal years is deeded into the name of the Clark County Treasurer as trustee.  These properties become eligible for sale at public auction unless the total amount owed is paid in full. 
The US Department of the Treasury auctions off “seized and forfeited” general property (fancy a Rolex watch or a Fender guitar?), cars (how about a pimped-out Escalade?) and boats. Visit the Treasury’s website to find more information on where and when these auctions are held, plus sign up for alerts and research how much money items have sold for in the past. In addition, the Treasury has real property (RP) auctions for real estate seized through IRS-Criminal Investigation, Immigration and Customs Enforcement, and the US Secret Service.
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 

Bidding. Get some information about the type of bidding that normally occurs at these auctions. Feel free to ask the consultant about the expected price of a particular vehicle. When the auction starts, raise your hand and registration number card high in the air so the auctioneer can see you. Bids can be in increments of $100, $250 or even $500. This will be up to the auctioneer's discretion. Before bidding, remember that once a bid is made it cannot be withdrawn. Once the bid is won then the bid cards must be immediately filled out and signed. If this is not done then the vehicle can be re-offered. The government can reject any bid
Auctioneers are normally contracted by the different organisations within their local area. An auction at the centre of London for example, will deal with the assets of companies whose bankruptcy proceedings are being dealt with by courts in Greater London. An auction in Leeds will handle the assets of companies in Yorkshire that are being dealt with by Leeds City Court.
