The Phone Bidder
The Phone Bidder
Anonymous, real-time bidding from anywhere via auction-house specialist
A phone bidder is an auction participant who bids on a lot remotely by telephone, connected during the live sale by an auction-house specialist who relays bids between the saleroom and the bidder. Phone bidding is the standard method by which serious buyers participate in major jewellery auctions without attending in person, and at the top end of the market — multi-million-dollar lots in Geneva, New York, and Hong Kong — phone bidders typically account for the majority of underbidders and frequently the buyer of the lot.
How phone bidding works
A buyer wishing to bid by phone registers with the auction house in advance of the sale, providing identification, financial references, and confirmation of the lots on which they wish to bid. The house assigns a specialist — frequently the head of department or a senior member of the team — to call the bidder when the relevant lot is approaching, and to conduct the bidding on the bidder's behalf during the lot's sale.
The specialist relays the auctioneer's calls in real time and conveys the bidder's instructions back to the saleroom by hand signal or paddle. The phone bidder remains anonymous to the saleroom audience, which sees only the specialist on the bank of phones. Bids are recorded by the auctioneer's clerk and are entered into the official record of the sale.
Why phone bidding matters
Phone bidding offers three principal advantages over alternative remote-bidding methods. It is anonymous, which serious collectors and investors typically value. It provides real-time participation in the live sale, allowing the bidder to react to bidding momentum, to the auctioneer's calls, and to any lot-by-lot dynamics in the saleroom. It allows the use of an experienced specialist as an intermediary, which is materially helpful in the heat of competitive bidding on a major lot.
By contrast, online bidding offers anonymity and real-time participation but does not provide an experienced intermediary; absentee bids — left in advance with a maximum amount — provide neither real-time participation nor the chance to adjust to the bidding environment.
Threshold and practice
Major auction houses including Christie's, Sotheby's, Phillips, and Bonhams offer phone bidding for lots typically estimated at or above a stated threshold, often around £10,000 or $10,000. For very high-value lots, multiple phone lines may be open simultaneously, with several specialists each working a different bidder.
The auction house's terms of business apply to phone bids in the same way as to in-person bids: the buyer is responsible for the hammer price plus the buyer's premium and any applicable taxes, and a successful bid creates a binding contract for the purchase of the lot.
In the trade
For serious buyers of important jewellery, registering for phone bidding with the auction houses is a basic professional practice. The relationship with the specialist team — who may also offer advice on estimates, condition, and post-sale services — is part of the value of phone bidding alongside the mechanical execution of the bid itself.
