question on pricing items

Hi-as stated on the chat board, we brought back lots of stuff from my Mom's house in So. Fla.  Some of the items are framed needlepoints.  I've checked E-bay, but the prices are all over the place.  Any of you know of any reliable spot for pricing vintage/antique needlepoint?  One of the lister's on E-bay even had one thing listed as "needlepoint" when it was obvious it was cross stitch.
Thanks!
