I'm Sandy Ludlum. I have been appraising natural history items for over 20 years. I am trained as a mineralogist, paleontologist, biologist, and appraiser.
I have written appraisals for single items and for entire museums and specialize in the following materials:
- MINERALS AND MINERAL COLLECTIONS
- VERTEBRATE AND INVERTEBRATE FOSSILS AND COLLECTIONS
- BUTTERFLY AND INSECT COLLECTIONS
- SEASHELL COLLECTIONS
- TAXIDERMY COLLECTIONS
- NATURAL HISTORY BOOKS

In general, I do not accept appraisal assignments for gemstones, lapidary material, or artifacts.
Non-appraisal services available include specimen identification, authentication, collection inventories, and cataloging.
