Toughest Bronze Age Marvels?

[hogations]

Okay, my take on the toughest Bronze Age Marvels in high grade:

 

4) Horror reprint titles - Vault of Evil, Uncanny Tales, Where Monsters Dwell, Beware, etc. I think I've found the later issues of Where Monsters Dwell and Weird Wonder Tales to be the toughest in high grade.

3) Short-run western titles like Gunhawks, Western Kid, Tex Dawson, Western Team-up etc. Wyatt Earp is pretty tough. 20 cent cover Kid Colt and Rawhide Kid are tough too.

2) Marvel's two romance titles, Our Love Story, My Love - later issues are very difficult.

1) Humour - Harvey, Millie the Model, Mad About Millie, L'il Kids and L'il Pals. There are later issues of Mad about Millie I've never seen in any grade, let alone in high grade (although they must turn up on eBay once in a while).
