My friend recently had two quilts appraised in Columbus, Ohio. I don't remember the names of the appraisers, but she was very satisfied with the information they were able to give her, and also the cost of the appraisals. It was very reasonable, especially if you didn't want a written appraisal for insurance purposes.
I can ask for the names, but she is currently out of town, so it may take me awhile. Perhaps other QB members from Ohio will know who I am talking about. I might recognize the names.
