Auction Formats

Consignment Auction

An auction format where multiple sellers (consignors) contribute items to a single sale, and the auction house manages cataloging, marketing, and sale execution. The auction house takes a commission (typically 20–30%) from each consignor's proceeds.

How It Works in Practice

Unlike estate sales (single-source), consignment auctions aggregate inventory from multiple sources — creating larger, more diverse catalogs that attract broader buyer pools. Regular consignment auctions (weekly or monthly) are the bread and butter of many auction houses, providing steady revenue and consistent buyer traffic. The cataloging challenge scales with consignment auctions: each consignor's items may arrive separately, requiring efficient intake, photography, and description workflows.

Frequently Asked Questions

How does a consignment auction differ from an estate sale?
An estate sale liquidates one household's belongings, usually on-site. A consignment auction aggregates items from multiple sellers into a single sale, typically at the auction house's facility. Consignment auctions offer larger, more diverse catalogs that attract more buyers, while estate auctions offer the charm and context of shopping in the original home.
What commission do consignment auctions charge?
Consignment auction commissions typically range from 20–30% of the hammer price, lower than the 30–35% standard for full-service estate sales. The lower rate reflects reduced services — the auction house doesn't sort, clean, or stage the consignor's home. Some houses offer sliding scales with lower rates for higher-value consignments.
