Green Dancer lamps

Always loved these lamps, and now they're mine. Just curious if these should be appraised or if their value is purely sentimental. (Not that I would sell them, I like them too much. They'd have to be worth a LOT lol.) I have the original shades in my car, they're huge and seem quite flammable. I think they're made of painted porcelain, they retain cold like porcelain. Had them in my car in the winter. I love the organic form of the background, I'm a horticulturalist. Any thoughts on these pieces would be appreciated! :)
