Golden Grape, Dugan
Found only in small (about 7 inch) bowls and an occasional rosebowl. I've never seen them in anything other than marigold, but Carl O. Burns reports amethyst and possibly green and Samantha Prince reports that she has a rosebowl in pink afterglow. The bowls are worth between $10 and $15; the rosebowls $20 to $25.

In 2011, a bowl in pink sold for $30.

In 2006, Don Hiltunen sent me this photo of a most unusual Golden Grape bowl with gold decoration.
