Antique auctions are events where valuable and unique items, often over 100 years old, are sold to the highest bidder. These items can include furniture, jewelry, art, and collectibles, attracting enthusiasts and collectors. Auctions can take place in person or online, allowing a wider audience to participate. Participants in antique auctions typically register beforehand and may receive a catalog listing the items available for bidding. Bidders can inspect items before the auction starts, and the auctioneer facilitates the bidding process. Successful bidders take home their purchases, often adding to their collections or investing in historical artifacts.
