I was wondering if a Secret Wars #8 cgc'd at 9.4 and signed by Michael Zeck and Stan Lee is worth $200 shipped? The reason I ask is I have an opportunity to purchase one, and being it has Stan Lee's signature on it I was highly interested, but it also has the Black Costume artist's signature as well. Just want to know what a fair price or round about price for a comic in this condition would be.
