Not sure if they could or would do a lot appraisal. I do know when I had my Agave Garden appraised in April a lot of other factors came into play besides just the quilt. I was asked questions like have I ever sold a quilt or ribboned at a quilt show.
The appraisal of the quilt about knocked my socks off (over $4K!!) but it was for insurance purposes not resale value which would probably be half of what the insurance replacement value was. Additionally she did mention on the write up that the market for quilts was very depressed right now. Appraisal for resale value will most likely come in quite low for that reason and the possibility of getting the appraised value of the quilt in selling them, due to current market conditions was equally low.
