How much should I sell a set of 4 of everything of Avon 1876 Cap Cod Dishes for?

I am trying to sell set of 1876 Cap Cod Collectors dishes from Avon but i'm not sure how much I should reasonably ask. I don't expect to get rich off them and i'm also not trying. I am going to sell them on Ebay; I figure that's easier than a garage sale. It is a set of 4 place settings with water goblets, wine goblets, dinner plates, dessert plates, dessert bowls, footed gles, napkin rings, tea cups and saucers. The set also includes a gravy boat, 2 serving bowls, 1 serving plate, a candy dish and a heart trinket box. The set has all the original boxes and they have never been used. They have only been setting in a china cabinet for almost 20 years. Thanks greatly!
