Key issue comics: common questions

What is a key issue comic?

A key issue is a comic collectors seek out for something that happens in it: most often a character’s first appearance, an origin, a death or a major event. Every key on this page says on its listing what makes it a key.

How do you decide which comics are keys?

Only key notes that passed our review are shown, and each one names the event, such as “1st full appearance of Venom”. A comic we couldn’t confirm isn’t marked as a key. Older keys are on the Silver Age and Bronze Age pages.

Are your key issues graded?

Most are raw copies with our own grade, shown with its range on the 10-point scale; slabbed copies show their grading company’s number instead. The grading guide explains each grade.
