Don't sell yourself short. You have put a lot of time making this quilt and the fabrics were a gift so it may mean a lot to you. It is a very nice quilt and you need to check around on like ebay and etsy to see what quilts like yours sell for. But---as someone told me a long time ago that it is your quilt and you can do whatever you feel comfortable. Good luck on your decision but the price someone offered is way too little for all the work you put into the quilt.
