I have the first appearance of Iron Man in Tales to Astonish but it is missing the front cover. I’ve been unable to ascertain it’s worth (if any). The remaining book is in good condition. Curious as to any advice or recommendations. TIA

Best bet is to bring it in so they can see it

You should take it in to show them. My personal opinion is that it does have some value. However, when I say some, I am not thinking very much.

Ebay sold listings of Tales of Suspense #39 (im guessing thats what you meant) show coverless copies going for around $400-600

Thanks for the advice. I’ve had 450 comics stored since the 60’s and 70’s and one of my children damaged just one book and that was the one:(
