What the list is

606 key issues across 200 series. It is the list Point and Sell's review screen checks each comic against.
Not on our list does not mean not a key. Plenty of keys are not on it, so check a price guide or another key list as well.
It says why an issue is a key, not what it sells for. The pricing guide covers finding that out.
Capitals and a leading "The" do not matter, and punctuation counts as a space, so "The Amazing Spider-Man" and "amazing spider man" are one series. "#300", "300" and "0300" are one issue.
A series that was started over can have more than one #1. Where the list knows which run an entry is for, it gives the years. Check the year on your cover.

As the list files them: lower case, with punctuation as spaces.
