How to Bid Online
Browse an auction

We encourage you to contact our specialists, whose contact information is included on the auction catalogue page. All property in the auction is available for viewing in our exhibitions or by appointment.

Place a bid through from the start of the auction until the lot closes. See below for how to bid in our online only and live auctions. Please contact us should you need any assistance.
Watch your bids! If you are outbid in an online only auction, you will be notified on the auction catalogue page and by email. In a live auction, you will be notified on the auction catalogue page, but not by email.
After your lot has closed, you will be notified on the auction and lot detail pages as well as via email. If you are the winning bidder, you will receive an invoice shortly after the auction including your total charges along with payment and property collection instructions.

Select the lots you wish to bid on and place your maximum bid. You will be asked to either log in or create a new account. You will then be asked to choose your account number and review and accept the Terms & Conditions before placing your first bid. The platform will place incremental bids on your behalf up to the maximum amount specified. Use the ‘Quick Bid’ feature to increase your bid to the next increment.


The closing time noted at the top of the auction page indicates when the first lot will begin to close. As the auction closes, a countdown timer will be displayed for each lot one minute before it closes. Each lot closes in one minute increments and will be extended by two minutes if a bid is placed within the final minute before the lot’s scheduled closing time. Lots may extend for up to two hours to accommodate competitive bidding.

There are four different ways to bid in a live auction: by telephone, online, and by either absentee or advance bidding ahead of the auction. You can register for telephone, online, via the Register to Bid link on the auction overview page. ‘Advance bids’ or ‘absentee bids’, both of which enable you to set your maximum bid on a lot, can be placed online or by contacting us ahead of the auction. Please note that auctions will either have advance bidding or absentee bidding, never both. At the stated date and time, a live auction will begin when the auctioneer opens each lot for bidding. Clients are able to participate by bidding by telephone, or online via Bids will be accepted in the order they are received and the highest bid placed will win each lot. When competitive bidding subsides, the auctioneer can send a ‘fair warning’ message to indicate that the lot will close imminently. Please note that placing the leading maximum bid before the live auction begins does not guarantee that another client will not outbid you before the auctioneer closes the lot.
Absentee bid: A maximum bid placed ahead of the auction which will be executed on your behalf by the auctioneer during the live auction, at the lowest price possible and never for more than the maximum bid amount you indicate. Successful absentee bidders will be notified after the auction.
Advance bid: A maximum bid placed ahead of the auction which will be executed on your behalf in response to any other bids placed on the lot. If your maximum bid is below the reserve, responsive bids may be placed by Iskenderian on behalf of the seller up to the amount of the reserve ahead of the live auction. Upon the start of the live auction, if your maximum bid has not yet been met, the auctioneer will execute the bid on your behalf at the lowest price possible and never for more than the maximum bid amount you indicate.

To place an ‘absentee bid’ or ‘advance bid’ ahead of the live auction, find your  desired lot and select ‘Place Bid.’ Set your maximum bid amount. Once you have chosen your bid amount, select ‘Continue to Confirm Bid.’ You will then be asked to either log in or sign up for a Iskenderian account. Select your Account to bid under, accept the Terms & Conditions, and confirm your bid. You will be asked to do this only once, upon placing your first bid in the auction. You will receive a confirmation of your absentee or advance bid on screen and via email. If you are outbid during this portion of the auction (before the live auction begins), you will receive notification on if you are logged in, via email. The advance and absentee portion of the auction will culminate in the live auction on the advertised date.
