Real property - Primarily, this consists of developed land with buildings, usually acquired by the federal government for a specific purpose, such as a military base or office building. This also includes some U.S. Forest Service properties, which usually consist of administrative sites and facilities. The General Services Administration (GSA) is the federal agency responsible for selling developed surplus property.  
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.

Due to the various governmental units that supply the vehicles for auction, there's no single reason for vehicles being brought to auction. Some of the vehicles are confiscated due to the former owner's involvement in drug dealing, smuggling, or fraud, while other vehicles were simply just abandoned. On exception, separate auctions will sometimes be held for very large seizures.
Many financial assets, especially government bonds, are issued by an auction. Animportant feature of the design is the auction pricing mechanism: Uniform vs.Discriminatory.

Combinatorial auction is any auction for the simultaneous sale of more than one item where bidders can place bids on an "all-or-nothing" basis on "packages" rather than just individual items. That is, a bidder can specify that he or she will pay for items A and B, but only if he or she gets both.[30] In combinatorial auctions, determining the winning bidder(s) can be a complex process where even the bidder with the highest individual bid is not guaranteed to win.[30] For example, in an auction with four items (W, X, Y and Z), if Bidder A offers $50 for items W & Y, Bidder B offers $30 for items W & X, Bidder C offers $5 for items X & Z and Bidder D offers $30 for items Y & Z, the winners will be Bidders B & D while Bidder A misses out because the combined bids of Bidders B & D is higher ($60) than for Bidders A and C ($55).
In the United States, a primary dealer is a bank or securities broker-dealer that is permitted to trade directly with the Federal Reserve System ("the Fed").[2] Such firms are required to make bids or offers when the Fed conducts open market operations, provide information to the Fed's open market trading desk, and to participate actively in U.S. Treasury securities auctions.[3] They consult with both the U.S. Treasury and the Fed about funding the budget deficit and implementing monetary policy. Many former employees of primary dealers work at the Treasury because of their expertise in the government debt markets, though the Fed avoids a similar revolving door policy.[4][5]
Whenever bidders at an auction are aware of the identity of the other bidders there is a risk that they will form a "ring" or "pool" and thus manipulate the auction result, a practice known as collusion. By agreeing to bid only against outsiders, never against members of the "ring", competition becomes weaker, which may dramatically affect the final price level. After the end of the official auction an unofficial auction may take place among the "ring" members. The difference in price between the two auctions could then be split among the members. This form of a ring was used as a central plot device in the opening episode of the 1979 British television series The House of Caradus, 'For Love or Money', uncovered by Helena Caradus on her return from Paris.
