Yur best bet is to take it to an antique dealer or even better an antique quilt dealer- to try and value a quilt sight unseen in person is impossible - also market has a lot to do with it . What might sell for good money in one area you might not be able to give away in another area. Factor in the economy and sadly that will bring down the value. I live near an Amish community and the quilts are all done by hand , piecing and quilting - and even they are taking a hit with the economy. Good Luck in your search for an answer
