The term "by the fall of the hammer" signifies that the auctioneer accepts the highest bid when the hammer drops to signal the end of the bidding for that item. This traditional practice indicates the moment at which the auctioneer considers the item sold, thus formalizing the agreement between the highest bidder and the seller. The action of the hammer falling is a clear and definitive signal, eliminating any ambiguity regarding the completion of the sale.
