Mystery auction is a type of auction where bidders bid for boxes or envelopes containing unspecified or underspecified items, usually on the hope that the items will be humorous, interesting, or valuable.[33][34] In the early days of eBay's popularity, sellers began promoting boxes or packages of random and usually low-value items not worth selling by themselves.[35]
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]
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 

Bids can be made online for Internet auctions, or in person for live auctions. Accepted forms of payment typically are major credit cards and checks, and payment is due at the time of the close of the auction. Details may vary among auction houses and the state the auction is held in. As with all auctions, the vehicle is sold to the highest bidder.

The auction marketplace serves both buyers and sellers, offering equally valuable, yet fundamentally different benefits to both audiences. To sellers, the auction marketplaces offers a fast, efficient way to convert physical property into immediate cash. For buyers, auctions offer the ability to get a variety of high-quality, sometimes rare goods for pennies on the dollar. Both groups benefit from expert appraisals, widespread marketing of new auctions, and the satisfaction of engaging in an environmentally-friendly way to reduce and reuse.
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.
Participants in any Treasury auction consist of small investors and institutional investors who submit bids categorized as either competitive or non-competitive tenders. Non-competitive tenders are submitted by smaller investors who are guaranteed to receive bills, but they won’t know what discount rate they will receive until the auction closes. In effect, these investors receive no guarantee on the price or discount received. An investor who submits a non-competitive bid agrees to accept whatever discount rate is decided at the auction, determined by the competitive side of the auction which is handled as a Dutch auction. The minimum non-competitive tender for a Treasury bill is $10,000. The non-competitive closing time for bills is normally 11:00 a.m. Eastern Time on auction day.

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.
