You're asking someone to put in a heck of a lot of work in all that question asking. I honestly got tired reading it, can't imagine answering all this. I think because you're asking so many questions you're gonna get a lot of snarky answers. This, I believe, is because people new (like yourself) barge in here and ask for someone to spend a lot of time to educate them. And than not even saying thank you afterwards. Not that I would accuse you of doing so, it's just a statistical thing. I see it happen, oh, 98% of the time. I'm just trying to explain the snarky s-storm that's brewing and will come on full force on about page 2 1/2, eventually locking the thread. Many, many collectors here have worked very hard to learn what they know. Spent a lot of money to learn what they know. Spent a lot of time to learn what they know. And now you're asking for them to just tell you, everything. Try to respect them and their time.
I want to welcome you here. Please stay and take your time with this hobby. Perhaps take a chill pill and ask a question or two. And say "Thank You" many, many times.
I'll put in a bit of effort here while I'm doing laundry so some other members can skip those questions and answer others.
The answers to many of your questions are subjective. Press any books you like. Prices are all over the place in comicdom now. Without a specific title and issue number it's hard to say if something will increase in value.
Again, I don't want to come off harsh. I want to welcome you and just try to explain the s-storm you dialed. BTW, what's your favorite storyline? Titles? Writers? Artists?
