Buying and selling, answered
How do I register to bid?
Create a free account, confirm your email and add a payment card. Registration for each sale opens two weeks before the auction and closes one hour before the first lot.
What is the buyer's premium?
The buyer's premium is added to the hammer price: 25% up to $500,000 and 20% above that. Online purchases carry an extra 3% platform fee.
How long does a free estimate take?
A specialist replies within five working days. Clear photographs of the front, back, marks and signatures help us give a reliable figure first time.
What does it cost to sell?
Our seller’s commission starts at 15% and falls for higher-value lots. Photography, cataloguing and marketing are included, and there is no fee if a lot does not sell.
Do you ship internationally?
Yes. Our shipping team packs and insures works for delivery to more than 60 countries and handles export paperwork where needed.
