How to Consign Fossils, Meteorites and Minerals
Selling with Lyon & Turnbull begins with a complimentary, confidential auction valuation.
Step 1: Contact Our Specialists
Complete our online valuation form or contact the Natural History team with details of the specimen or collection you are considering selling.
Step 2: Send Photographs and Information
Where possible, include clear photographs showing the complete specimen, its approximate dimensions and any identifying labels or documentation. Details of its origin, previous ownership or acquisition history are also helpful.
For larger collections, an overview of the material and photographs of representative specimens provide a useful starting point.
Step 3: Receive Specialist Advice
Our specialists will review your enquiry and advise on the suitability of your material for auction. Where appropriate, they will discuss an auction estimate, consignment arrangements and the next steps.
Step 4: Prepare for Auction
Once accepted, your consignment will be professionally catalogued and photographed ahead of the sale, with marketing designed to introduce it to relevant collectors.
Consignments Invited for February 2027
Our Fossils, Minerals & Natural History auction opens online on 04 February 2027 and closes on 25 February 2027.
We are currently accepting enquiries for inclusion in the sale. As cataloguing and photography take place ahead of the auction, we encourage prospective sellers to contact our specialists as early as possible. If you have fossils, meteorites, minerals or a natural history collection you are considering selling, contact Alexander Tweedy and the Natural History team for a complimentary valuation.
“Natural history offers an extraordinary breadth of collecting, from fossils that reveal life millions of years ago to meteorites that have travelled across our solar system. With our first dedicated Fossils, Minerals & Natural History auction, we’re looking forward to introducing these remarkable specimens to a wider audience of collectors, while offering owners a specialist platform through which to sell.”
