Frequently Asked Questions
Where should I sell my Natural and Earth Science objects?
Sotheby's experts have been evaluating fossils, minerals and meteorites for many years, and our specialists are distinguished experts in their field. Our free auction estimate process is easy and confidential to ensure that you can quickly receive a Sotheby’s valuation. When you are ready to consign a dinosaur artefact, prehistoric animal skeleton or gogotte formation, your dedicated specialist will help you navigate the auction consignment process to make it as seamless as possible.
Why are prehistoric Natural History artifacts valuable?
Rare examples of nature’s prehistoric artwork are in demand worldwide because so few of these ancient artifacts exist. For example, serious science buffs collect meteorites, with some specimens dated at more than four billion years old. Mineral specimens and agate slices are also highly desirable for their natural beauty and scientific interest.
What types of Natural Science objects are in demand?
Passionate collectors bid competitively for important examples of natural science such as a fossil, extinct animal skeleton, dinosaur relic or fossilized wood. These might include a fish fossil, trilobite fossil, ichthyosaur fossil, marine skeleton, fossilized shells, animal skeleton, prehistoric egg, megalodon tooth or petrified wood.
How does Sotheby's determine the value of my Natural Science objects?
Sotheby's specialists have decades of experience in evaluating fossils, meteorites and minerals. Simply submit clear photographs of the front and back of your rare natural artefact and our specialists will carefully review the object and determine its value.
