Here some info for you on available editions. https://illustrated007.blogspot.com/2010/03/dr-no-comic-adaptation.html
It's been a while since I've seen one come up for grabs, IIRC it was on offer for £300-400 ($390-525) on ebay, and I think a VG, whether it sold or not I couldn't say.
Here's an Aussie edition that sold back in September, more reasonably priced https://www.ebay.co.uk/itm/original-rare-158A-Classics-illustrated-Dr-No-vintage-comic-UK-australian-copy-/254362711438?hash=item3b3932f58e%3Ag%3AIesAAOSwlf5dZDRj&nma=true&si=M2rXhFZjfGO2ru1ret1SAV0mTDQ%3D
