I have repaired a couple of antique quilts for my friends. One by taking old material and appliquéing it with a blind stitch to the damaged part then re-quilted it without a frame. I didn't use a frame because I was afraid of pulling on the material and damaging it more. The other had damaged to the binding. On that one I took a seam ripper and broke some of the top sides away from the back, cut off the bad part then refolded the back over to make the binding. The quilts were sentimental to both my friends so they were very happy to have them repaired.
I live fairly close to Raleigh also. I have seen badly damaged quilts go for a hundred at an estate auction and seen them go for five at the flea market. If you want to sell them online just see what others cutters quilts are selling for. Good luck with whatever you decide to do.
