The ballpark cost Kris is being given of $30,000 is in line with the quotes a friend has received to make the mold for a new product he's bringing to market. Simple math tells you the breakeven point is around 100 at $300 per eagle. A reproducer would probably make far more then that.
The confounding point to me, and Houston alluded to it above, is these eagles are scarce. If several hundred had been made and sold I think you would see a lot more of them available.
BTW JR: You really should have bought the model train with the eagles on it I found last year! Smile
