72 GS grill

I have a 72 NOS GS grill,still in the box.I know the 71 grills are bringing big bucks,how much do you guys and gals think this may be worth?I got this in a "package" deal,and not sure what I want to do with it.Any input would be helpful.

Thanks for your time.

 

My guess is about $550 to $600

 

Thanks Phil. Wonder why there is such a price difference? Availability? Demand?
o No:

 

71 GS grille is unique to the GS. 72's are the same between GS and base plastic skylark. (except paint).

 

Maybe 250-350 is my guess
