Recently, I stumbled across a set of 9 Vogue Ginny Dolls.  They are in fair shape but have some what is called "greening" which means that some of their little hands are turning greenish.  It's apparently something that happens to this type of doll.

I'm wondering how much the greening effects the value.

Does anyone else in adland know about these dolls or how to evaluate their value?  Thanking you in advance, NJ
