If indeed a Fenton lamp the price would start around $250.00 & up depending on age & if in fact it is Fenton. The shade is what seems to be burmese glass, In 1885, Frederick Shirley, an Englishman who immigrated to America, patented the formula for an opaque, heat-sensitive glass which, when warmed-it, shaded from lemon yellow to salmon pink. In 1969, after many trials, Fenton chemist Charles Goe replicated Shirley's formula, & it has become one of the most collectible Fenton colors. Burmese contains pure gold, & careful reheating coaxes the delicate pink shading into existence. The yellow color comes from a small amount of depleted uranium in the batch. Over the years, there has been variation in the color of the yellow from greenish to a cream hue. It is called Burmese glass due to Queen Victoria, she thought the color reminded her of a Burmese sunset.
