Hello, I inherited a set of Rosenthal China with the marking and pattern pictured. The pattern is a periwinkle blue and beige/gold floral design. I believe it is circa 1945. Each place setting includes dinner plate, salad plate, dessert plate, soup bowl, finger bowl, teacup, and saucer. The set also includes a tea/coffee pot, sugar bowl and cream pitcher, gravy boat, two large serving bowls, one large serving bowl with lid, and set of 3 multi size serving platters. The majority of the items have little to no damage. Approximately what could I expect an antique dealer or auction site to offer for this set? Thank you!
