In October 2023, a resident of Milwaukee, Wisconsin, inherited a copy of Amazing Fantasy #15 from a deceased relative. This rare 1962 comic book marks the first appearance of Spider-Man. With a CGC grade of 4.0, it could fetch around $35,000, aligning with the current market value. In contrast, a near-pristine copy of the same issue sold for a staggering $3.6 million in 2021. If you’re serious about investing in valuable comics or looking to enter the collectibles market, investing in a durable safe to protect your collection is a smart move.

Heavy Duty Safes to Protect Valuable Comics
I only recommend purchasing one of the safes on this list if you have extremely valuable comic books or collectibles that need protection. A large safe serves as both a security measure and an insurance policy, but only if it’s safeguarding something truly valuable.
Additionally, keep your expensive collectibles, safe, and home security measures private. The effectiveness of your security is compromised if too many people know what you own or where you store it.
