What do you call an auction caller?
Bid Caller: The person who actually calls, cries or auctions the property at an auction, recognizing bidders and acknowledging the highest bidder. Commonly known as the auctioneer. However, unlike traditional or live auctions, there is no auctioneer present. Instead, participants place their bids silently and anonymously on a bid sheet using a bidding number—hence the name silent auction.
