Unusual Eyeball Marble Find......any clues on age?

[starwarsblazer]

I found this marble while removing dirt from the foundation around a barn on my aunt's property. I had to fill some cracks in the cement and this marble was in one of the mounds of dirt that I pulled out. I have no idea if it is old, but it does have an unusual shape. It is teardrop shape. I have never seen any marbles like this. It is blue and white swirl. Any clues?

It's old. Most marbles today are uniform and massed produced. This looks hand made. Which I knew more about marbles. I am sure someone has a web site for old marbles.
