If you don’t mind a 9.4, then Transformers #1 for nostalgia purposes works for me (I was born in 77). This is one of the first books I owned and anything Transformers ruled my childhood.
I’m also hunting down a slabbed DC Presents 52 and/or Ambush Bug 1. He was my Deadpool back in the day.
I can see DC’s new corporate overlords looking at Marvel and saying “Disney’s got Deadpool” where’s our Deadpool. Then someone says, we got Harley Quinn. Then someone else says, “No, wait, audiences are going to be confused with Margot Robbie’s Harley Quinn. What else you got?” Then someone else says “I got it! Mister Mxyzptlk!” Then someone from marketing starts sobbing (It’s not clear if it’s from laughing or out of frustration or both.). Finally, someone says “Ambush Bug!” Everyone says “Who?” and pulls out their phones to bring up the wiki page. The inventory guy smiles thinking about all the molding dolls he has in a warehouse that he can repurpose and sell. Then the Hollywood folks start imagining how they would sell this to Ryan Reynolds: “Just do Deadpool with a green mask and with more fumbling. Ryan, this is your chance to wear green in DC again and redeem yourself. Just like you did with Deadpool!”
