My friend was recently in this same situation. She inherited a crazy quilt from her MIL. With my help, she found local appraisers (Well, 2 hours away). They did not feel confident to give her an appraisal of this unique quilt. (It was beautiful). The appraisers suggested she contact an appraiser in California, who had some expertise in this area. It was appraised for several thousand dollars, and the California appraiser helped her find a buyer. It was worth her time and expense to do a thorough job researching her quilt.
