How much a nice sharktooth grill go for?

I have a sharktooth grill that needs one turn lense (small spider cracks), two small fins missing, and two broken tabs that I bought a year ago from a collector for $400. I don't know if I just got a good deal or what, but I have seen 2 mint grills priced at $800 and $950 and neither one sold. So I guess how quickly you wanna sell it would influence your pricing. I hope this helped.

I'm actually looking for a sharktooth grill thats busted up to use as a donor for parts or I may even buy a near mint one. Do you have a donor grill?
