I don't really know. But I will say that the everyday public doesn't seem to understand that antiques and collectibles which they own may be valuable, but there still needs to be a market for them. Dealers aren't usually interested in things which don't have a strong potential for resale. I recommend throwing your stuff up on eBay for a low price (start at most at a third of the worth you think they have). Norman Rockwell isn't having a surge of popularity currently.
