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.

Key Collector Comics has an average rating of 4.8 out of 5 stars on the Apple and Android stores. 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.

Great App, Great Features, Worth It’s Weight


So, downloaded the app to find all the first appearances of my favs and especially stuff I didn’t know about. App did great at digging down and catching the B players that always get missed but get played in the after movie credits. Liked the app then

Then they added the Key Alert with the paid subscription. Paid the measly, almost comically low price, got three alerts, ordered the books before the public knew and paid for my subscription for the next 5 years!! Love the app now. Like truly, if you speculate and you don’t have this app..thanks, more for me. They’re still updating but even now, nothing beats it.

Get em BEFORE their hot!


Yes this has an ever-growing database of keys for hundreds of characters across several universes, yes it is constantly updated with new contests and giveaways, yes I spend hours just looking through the comics related to different characters, learning things I didn’t know before... but what I love the most about this app is that it sends me notifications as soon as news happens as to what key comic is related to the news so I can seek out the comic and snatch it up before it gets hot. It really is an innovative app and a great way to keep track which keys you have and which ones you want. And definite MUST HAVE for any comic books collector or fan!

Collecting and Logging Key Comics The Easy Way


As an on and off comic collector spanning over three decades, one of the things that I had difficulties with was trying to figure out which comics were considered key issues. This was especially problematic once I started to go to comic cons, never knowing which ones I should bring to get it signed and graded. This problem went away when the Key Collector Comics app was created. It has dramatically cut down on the search by...well, a lot. And even better is being able to log which comics I own or want. This is a must own app for all comic collectors out there.
