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]

Property becomes tax-defaulted land if property taxes remain unpaid at 12:01 a.m. on July 1st.  Property that is tax-defaulted after five years (or three years in the case of property also subject to a nuisance abatement lien) becomes subject to the county tax collector’s power to sell that property in order to satisfy the defaulted property taxes. The county tax collector must attempt to sell the property within four years of becoming subject to sale.
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!
Walrasian auction or Walrasian tâtonnement is an auction in which the auctioneer takes bids from both buyers and sellers in a market of multiple goods.[46] The auctioneer progressively either raises or drops the current proposed price depending on the bids of both buyers and sellers, the auction concluding when supply and demand exactly balance.[47] As a high price tends to dampen demand while a low price tends to increase demand, in theory there is a particular price somewhere in the middle where supply and demand will match.[46]

Private treaty sales – Occasionally, when looking at an auction catalogue some of the items have been withdrawn. Usually these goods have been sold by 'private treaty'. This means that the goods have already been sold off, usually to a trader or dealer on a private, behind-the-scenes basis before they have had a chance to be offered at the auction sale. These goods are rarely in single lots – photocopiers or fax machines would generally be sold in bulk lots.
At times, customs may decide to not only seize goods but detain the passenger as well. This can happen for a number of different reasons. One reason is if, as mentioned above, a passenger has not declared the item(s) or if they have been declared falsely. Another reason would be if an individual carried with them over 200 grams of tobacco or a very large amount of alcohol.
