What defects / grade can you live with?
For reference, I have collected vintage baseball cards for quite a while. Graded vintage baseball cards. I have recently started to pick up the occasional graded comic. I am looking for some knowledge/opinions when it comes to comic book collecting and grading.
My first question is, what defects can you live with? spine stress? chipping? tears? etc....
Second question is, what grade is acceptable for you? I know that the age of the comic comes into play, but for most collectors, is there a grade that you stick your nose up at?
For example, I recently just bought asm #300. It is graded an 8.5. I bought the graders notes and it was docked for "spine stress lines breaks color". This defect looks relatively small and does not appear to take away from a nice looking cover. I found it to be acceptable.
Now with that example, would that score/graders notes turn you off from a comic? I'm just trying to get an understanding of how this community views defects/grading compared to the baseball card community. I'm trying to be a sponge and soak up as much knowledge as possible.
