On occasion, I wear the hat of Rare Book Appraiser.  Appraisals and simple valuation reviews can be done for current market value, IRS and/or insurance purposes.   Please contact us for more information and/or to schedule an appointment to discuss your specific appraisal needs.  If something falls outside the bounds of our expertise, we are happy to make the proper referrals.
