those have been getting those prices for quite awhile now, but one i never see mentioned much is asm 601. that book is starting to sell over 30 pretty regularly now too, but it never gets as much attention as all the black cat covers for some reason.
it is reaching iconic cover status imo, and only getting more popular, you see tons of cosplayers recreating that cover now.
Yes, 606 & -07 have been hot for a while. I have been grabbing any 50-52 / 490-92 & 601 I can find as well. They are all J. Scott Campbell covers which is part of the appeal.
611 w/Deadpool and 640 Women of Marvel Variant are good ones too.
This book has been hot. I consider captain Britain #8 to be her first appearance though.
Copper books. NM Annual #2 is the 1st US printed appearance and Britain #8 is hard to find and usually out of the price range of modest collectors.
So Britain 8 is the first appearance?
1st appearance of Elizabeth, yes.
New Mutants Annual #2 is the 1st appearance of Elizabeth in the regular US Marvel world.
X-Men #256 is the 1st appearance of Psylocke as the Asian we all come to know and love.
