Hobnail, Imperial
Five inches tall, these bells were produced in marigold (Rubigold), smoke (Peacock), amber, and pink. The IG mark is difficult to find; it's on the stem just below the finial (see inset). Most sell in the $15 to $25 range, pink a little less. Note the similarity of the compotes to the bells. The compotes are much more scarce than the bells and only listed in amber. The one shown above sold on eBay in 2003 for $25.
These 12-inch tall oil lamps are found in amber (shown), marigold, and smoke. This one sold for $105 in 1999; a smoke example brought $45 at the same auction. Two others sold on eBay in 2004 for $58 and $80. A similar marigold example sold at live auction in 2005 for $40.
