Alley St.Marys Ghost. They are everywhere, and always have been since I have been with marbles. About as abundant as a MK Bumblebee. They were named(not me)about 14-15 years ago. But the last five years people have went nuts buying them and paying from $5.00 to $25.00. for one. If there is a$1.00 or 4 for $1.00 box with 300-1000 marbles at a show, these will be in the box. They have slowed down on price so I guess people are satisfied now, they have a Alley St.Marys Ghost. The base is clear with thin blue and red swirling. The blue and red will vary some depending on how heavy or thick the blue or red color was added plus temperature. With the numbers he made these often and probably over a few years at St.Marys. There is a Jabo that is similar but both colors are more heavy or brighter, more blue and more red. Jabo also had a blue base with some clear and thin red added which burnt. These can look like Alley Ghost.
