|These spittoons, with the ribs on the interior, are found in a variety of top configurations; 3, 4, or six ruffled, 2 sides up, 3 sides folded in, and 4 sides folded in. Most collectors consider these to be Dugan, but there is no definitive evidence for attribution to any company. I've only seen these spittoons in marigold. They sell at auction for between $100 and $200. Those with the more exotic tops, like that at top right, would no doubt bring more. The example at the right, in aqua opal, was listed as Ruffled Rib at the 2003 auction where it brought $875. However, the pattern is clearly different, with a larger base and fewer ribs, so it's not the pattern traditionally referred to as Ruffled Rib.
