Birmingham-based auction house SDL Bigwood raised more than £15m at its latest sale.
Out of 129 lots offered, 106 sold – an 83% success rate and its second-best sales result.
Head of auctions Jonnie Hackett said: “Any trepidation we may have had about our first auction after the referendum vote was swept aside as soon as bidding started.”
