About Icon


This is the most important resource for comic collectors since the Overstreet Price Guide.
Key Collector Comics is a free mobile app that focuses exclusively on identifying which comics are the key issues from the Golden Age of comics up until today.

There are over 10,000 comics that have been identified as a “key” including character first appearances, origin stories, iconic cover art and any milestone moment in comics that make an issue valuable or define a character and the universe in which they exist.

Use Key Collector Comics when you’re flipping through a long box to make certain you don’t let anything valuable or interesting slip past you. There is also a simplified price guide for ungraded books to quickly reference when making a purchase. You can also inventory what key issues you own or build a wish list for the books you want.

It has been endorsed by Alex Ross and Neal Adams who often do giveaways on the app. There are no advertisements and no dollar bin drek. Just keys, no clutter.
