Whether it is your first time bidding at an auction or you are a long-time customer, the resources on this page will assist you during different steps of the auction process. We want our customers to feel well-informed and confident before participating in our auctions.

Types of Auctions

Live Auction

A live auction is an auction that is taking place in the present, and all bids are in real-time. Typically, you can participate in these auctions either online or on-site unless otherwise noted.

Timed Auctions

A timed auction is an auction taking place online only over a period of time and closes at the end of that time period, i.e., one week.


Methods of Bidding


To bid online, you must sign up online to create an account and then register for the auction of your choice. Online bidding can take place with live or timed auctions. Please register as early as possible, as we cannot guarantee approval if you register the day of the auction.


To bid on-site, you will register on the day of the auction in-person at the auction location with our auction manager. Once you have registered and been approved, a buyer number will be assigned to you, and you will be ready to begin bidding.

Proxy Bid/Absentee Bid

If you cannot participate on-site or online, a bidder can submit a maximum bid amount by submitting a proxy bid form via fax to 708-343-7100 or email to auctionservices@centurionservice. You can also place absentee bids directly on our website by viewing the online catalog for the auction of your choice. We act as your representative at the auction and buy the lots/items as cheaply as competition permits. Click here to download the proxy bid form.

Auction Terminology

“as-is where-is” – The item is sold in its present condition, with no return privileges.

“Lot” – Item(s) being auctioned. An auctioneer can announce one lot number or multiple lot numbers.

“So much a piece times the money” – The auctioneer is asking the winning bidder to choose how many of the like items they want to be multiplied by the winning bid amount.

“Option” – The winning bidder has the option of choosing how many of the items being sold they want. The items MUST be selected in numeric order.

“Group” –  Multiple lots are being sold for one price. The winning bidder will receive all items within the grouped lots.

“Pass” – If an item is up for auction and there are no bids or the bidding does not start at a number deemed acceptable by the auctioneer, the item will be passed.

“Buyers Premium” – A fee that Centurion Service Group charges for conducting an auction.

“Proxy Bid/Absentee Bid” – Allows a bidder to place a bid without being present for the live auction. A bidder will submit the maximum price that they are willing to pay for an item and allows Centurion Service Group to bid on his/her behalf, up to the maximum bid amount. Centurion Service Group does not start bids at the maximum bid price.
