The process begins several days before the scheduled auction when the Treasury announces the details of the upcoming issue, including the amount to be auctioned and the maturity date. When you participate in an auction, you have two bidding options – competitive and noncompetitive. TreasuryDirect allows noncompetitive bidding only. Noncompetitive bidding is limited to purchases of $5 million per auction. Bidding limits apply cumulatively to all methods (TreasuryDirect, banks, and brokers) that are used for bidding in a single auction. 

From our early days as an online police auction site, there was one piece of property & evidence that we did not touch – firearms. However, recently for many states and jurisdictions it has become a requirement, and even mandated, for law enforcement agencies to auction off their seized, forfeited and unclaimed firearms just as they do with other parts of the property and evidence room.
... Back and Zender (1993) andWang and Zender (2002)illustrate the nature of these equilibria and discuss the difficulties associated with drawing sharp comparisons across the pricing rules. 1 Empirically, there are limited and conflicting results concerning the relative attractiveness of the different auction formats (compare Simon (1992) to Umlauf (1993) andTenorio (1993)). In practice, even in the relatively simple realm of government debt auctions, different countries use different types of auctions (seeBrenner, Galai, and Sade (2009)). The importance of effective governmental borrowing in the remedies to the world financial crisis serves as a reminder of the importance of developing our understanding of this important market mechanism. ...
Many financial assets, especially government bonds, are issued by an auction. An important feature of the design is the auction pricing mechanism: Uniform vs. Discriminatory. Theoretical papers do not provide a definite answer regarding the dominance of one type of auction over the other. We investigate the revealed preferences of the issuers by surveying the sovereign issuers that conduct auctions. We find that the majority of the issuers/countries in our sample use a discriminatory auction mechanism for issuing government debt. We use a multinomial logit procedure and discriminatory analysis to investigate the mechanism choice. It was interesting to find that market oriented economies and those that practice Common law tend to use a uniform method while economies who are less market oriented and practice Civil law tend to use discriminatory price auctions.
By the end of the 18th century, auctions of art works were commonly held in taverns and coffeehouses. These auctions were held daily, and auction catalogs were printed to announce available items. In some cases these catalogs were elaborate works of art themselves, containing considerable detail about the items being auctioned. At this time, Christie's established a reputation as a leading auction house, taking advantage of London's status as the major centre of the international art trade after the French Revolution.
Reserve auction is an auction where the item for sale may not be sold if the final bid is not high enough to satisfy the seller; that is, the seller reserves the right to accept or reject the highest bid.[37] In these cases a set 'reserve' price known to the auctioneer, but not necessarily to the bidders, may have been set, below which the item may not be sold.[36] If the seller announces to the bidders the reserve price, it is a public reserve price auction.[39] In contrast, if the seller does not announce the reserve price before the sale but only after the sale, it is a secret reserve price auction.[40] The reserve price may be fixed or discretionary. In the latter case, the decision to accept a bid is deferred to the auctioneer, who may accept a bid that is marginally below it. A reserve auction is safer for the seller than a no-reserve auction as they are not required to accept a low bid, but this could result in a lower final price if less interest is generated in the sale.[37]
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.
Once a car has served its time, it’s stripped of all its Police markings, siren, radio, gun box and serviced, before going under the hammer. These vehicles may have done more miles than your average family runabout but, Police Cars are kept in tip-top condition. No expense is spared in keeping these motors immaculate and they receive the best parts, tyres, even oil.
You can find some information online, on government websites which will let you search your area for a particular vehicle. These sites are not limited to cars, either. You can find SUVs, trucks and motorcycles on many of them too. Doing a ZIP code search and choosing a specific model will show you all the vehicles within a certain distance from you. Police specific auctions can be found by other websites like gov-auctions, which tells you when and where the local auctions will take place.
