What is Sealed?
Sealed is RM Sotheby's dedicated Private Sales and Sealed Auctions division. Discretion has been part of RM Sotheby's business since 1976, when the company began facilitating off-market transactions alongside its public auctions. Sealed brings that experience together in a single platform built for collectors who value privacy, curation, and a fully managed transaction from first enquiry to delivery.
At its core, Sealed offers two routes to market: private treaty sales, negotiated discreetly on a collector's behalf, and our proprietary sealed bid auctions, the first of its kind in the industry. Both are backed by RM Sotheby's and Sotheby’s global network, specialist expertise, and a century-spanning record in the collector car world.
