Bob Griffis Minerals

Bob Griffis Minerals is owned by Bob and Sarah Griffis, and we have been buying and selling mineral specimens since 1978, and on the web since 1995. Over the years we have dealt in several large collections, including university and estate consignments. If you have a collection you would like to sell or consign, please contact us.

We offer full appraisal services for your mineral collection, including appraisals for insurance (replacement cost) and for donations (IRS fair market value). Please click here for a more complete description of our services.
