‘Action Comics’#7
In 2018, a copy of “Action Comics” #7 sold at auction for $160,000, making this a fairly pricey comic book. Even rarer, though, is the “ashcan” version of this book. An ashcan comic is a rough, black-and-white copy of an issue that’s made as a draft before the color version goes to print. They’re designed to be thrown away upon completion, i.e., tossed into the ashcan, hence the name. Some of these ashcan comics still exist, and an ashcan “Action Comics” #7 is still somewhere out in the wild. Good luck finding it, though, as likely only a single copy exists in the entire world.
