Consignment-type auctions typically involve accepting firearms from:

Consignment-type auctions are designed to facilitate the sale of items from various owners, allowing multiple individuals to submit their items for auction. This approach enables auctioneers to present a diverse range of products, which can attract a wider audience and increase competition among bidders.

Accepting firearms from multiple owners allows each owner to capitalize on the collective interest and demand during the auction, potentially leading to higher sale prices. This practice also reflects the unique nature of consignment auctions, where the auctioneer acts as an intermediary between various sellers and buyers rather than representing a single entity or owner.

On the other hand, limiting the consignment to just one owner, a single auction house, or only government entities would restrict the auction's variety and appeal. Government entities might be involved in some situations, but consignment auctions typically encourage participation from any individuals wishing to sell their firearms. Therefore, accepting firearms from multiple owners aligns with the fundamental principles of a consignment auction, enhancing the overall auction experience for everyone involved.
