Is this quilt an imported one from about 20 years ago? They were often finished without binding.
I don't recognize the fabrics; imports are often made with "similars" but not American designed fabric.
Was it handquilted with big stitches that are somewhat uneven? The skill level of the original workers in the "quilt trade" (many of whom were virtual slave laborers) was quite poor. It has improved over the years.
The pattern is also somewhat unfamiliar. Many of the early imports were designed overseas and did not look like ours, though this one is really quite interesting.
Is the batting polyester? Most of the early imports used poly exclusively. It also allowed for wide unquilted areas as this photo appears to have.
IF you think it might be an import rather a true American quilt, taking it apart to repair, to rebatt if you desire, and even to use a binding, would definitely improve it and would not hurt the value.
