Your globe is original any 7" base crown is original. 99% of any threaded base crowns are original. Any 6" base crown is phony. Now it was painted at one time so technically it's not a "White Crown" but could have been another color. Still original though. Did you say blue specks? If so it was blue at one time. Since all the paint is gone not a lot of value. $650-$700 retail tops. I collect crowns and washed out crowns are very common, as are Gold, Red and pure White ones. Original paint Blue, Green, Gray and the early raised letter ones have much more value. Blue Crowns were used in the 1930s/40s. Pure White 1930-1955, Gold after 1956. Red from 1930 or so into the late 1950s...The raised letter crowns are all from the 1920s and the early etched ones 1910s...Been collecting for nearly 50 years I buy and sell original globes too...
