Online stamp auction (online auction) - an auction held via the Internet. Unlike conventional auctions, online auctions are held at a distance (remotely) and you can participate in them, not being in a certain venue, making bids through the website or a special computer program of the auction.

The main structural unit on the online auction is a lot. Lot - publication of information on the sale of a particular product, or group of goods, placed in the online auction system. The seller describes the goods, if possible, adding a real photo of the lot to be exposed.

Online auction allows you to track ratings and reputation of bidders, provide a platform for payment and dispute resolution. Due to the use of the international telecommunications network “Internet”, the circle of potential buyers is significantly expanding.

Main types of stamp auctions

Standard stamp auction

The auction of the seller to increase the initial price, sometimes also the "English auction". The seller when placing the valuable lot, indicates the initial price and the duration of the auction. During the auction, potential buyers send their bids through the auction system, sometimes using automated software (bots). Usually the price of the highest bid is public. The winner of the auction will be the participant whose bid is the highest at the time of the end of the auction for the lot. In many systems, the seller can also assign a "blitz-price." If the buyer places a bid in the amount of blitz prices, the bidding ends early, and he is automatically recognized as the winner of the bidding.

The prevalence of the scheme and the popularity of the exact time of the end of the auction led to the emergence of such a phenomenon as Auction sniping [ru], when the rate is made in the last moments before the end of the auction for the lot.

Standard stamp auction can be held in a modified form, when a small amount is charged to buyers for each bid.

Dutch auction

The opposite of a standard auction is the so-called Dutch auction, during which a price reduction occurs. When placing a lot, the seller indicates the initial and minimum price and the duration of the auction. The trading system produces multiple decreases in the lot price. The buyer may agree to buy the lot at the current price, after which the bidding ends, and he becomes the winner of the bidding.

Auction with closed bids

Blind auction (FPSBA) is conducted in the same way as a standard stamp auction, however, information about user bids is hidden, and buyers can usually choose only one price for a bid. Wins the highest bid. Game theory shows the equivalence of the strategies of a blind auction and a Dutch auction.

Buying rare stamps at auction
