There are a few legitimate old greens with blue eyes, but they are extremely rare. However fakes of this color with blue eyes are extremely common. You can tell the fakes by the green felt on the bottom, the bulging blue eyes (which are actually plastic), and the light purple gems. If you look closely at the pictures, you will often notice that there are bubbles in the plaster, certain parts are mishapen, and the paint jobs are not as good.
I’m pretty familiar with these fakes (I own one), and the one on ebay is definitely a fake.
