Help with value ET figurines in different production phases.

[chiller1]

My uncle was an Operations Manager for LJN Toys in Lyndhurst N.J. When his company came out with the ET figures in 1982, he gave me the figures in 3 different phases of production. Black mold, Tan painted and finished version. I have several of these unique production line examples and am wondering if anyone can give me an idea on value? I have not been able to locate any other production stage figures available anywhere. Thanks for assistance

I don't think there's much demand for ET merchandise per se (but I could be wrong), but pre-production pieces generally seem to fetch several hundred apiece at least.
