By displaying the SAiMP badge next to certain auctions, OneBid draws users’ attention to sales organized by entities whose founders are members of the Polish Association of Antiquarians and Art Dealers (SAiMP). This is the largest and oldest organization uniting owners of businesses operating in the Polish art market, including auction houses, galleries, and antiques dealers. Members of the association follow professional ethics in their work, promoting the development of a safe and transparent art and collectibles market in Poland. Information about a seller’s membership in SAiMP enhances the sense of trust and security for collectors making a purchase.
