Sure, comics are often seen as collectible. The collectibility of comics depends on factors like their condition, publication date, the popularity of the characters or story, and the demand among collectors. A comic in excellent condition from an early era or featuring a key moment in a comic universe can be quite valuable and collectible.
The key to displaying collectible comics is to make them stand out. Maybe put them in clear plastic sleeves and then stack them neatly on a table. Or, you could build a custom display stand with compartments for each comic. It all depends on your space and personal style.
One option could be to look for them at the weekend flea markets or collector conventions that sometimes happen in Madison. Also, check out online marketplaces that have sellers based in Madison, WI.
