your copy of Punch 12 is one of the nicest I have seen "in person"... I am aware of the MH copy and I think the crowley is a 8.0, right , but I believe yours is the second nicest copy cgc has slabbed, and my guess is there are only a handful of "fine" or better copies out there...I have searched for years for a nice copy, and until you posted yours, I had only seen one other nicer other than 2 peds mentioned (but it has some black color touch)
now, I have seen a fair number of low to mid grade (heck, one boardie alone owns like, what, 4 copies)...I had a couple of low grades (I only have one 3.0 ish copy now I would LOVE to upgrade), and I believe parker sold the 5.0? brittle paged copy back to mcmiles (that one looks much higher, but PQ brings it down)...
very tough book, and even tougher in nice condition... yours is definitely top 5 "known" copies imo
