Gaming items were never supposed to pay rent, but here we are. Back then, you opened everything, threw away boxes, and used cartridges like they were indestructible bricks. Nobody told you that “keeping it sealed” was basically investing. Now those same things you traded, scratched, or lost under the bed are selling for ridiculous money. The worst part isn’t the price… it’s realizing you probably had one. This list is a mix of regret, nostalgia, and that uncomfortable feeling of “yeah… I had that”. And no, checking your old drawer won’t hurt… probably.
1. Pokémon Crystal Version (Game Boy Color, 2000)
A loose cartridge is nothing special, but a complete or sealed copy is where things change. These gaming items can reach between $800 and $5,000 depending on condition, mostly because people actually played them instead of preserving them.
2. Game Boy Advance SP Tribal Edition (2003)
That weird tribal design you either loved or hated? Turns out it didn’t sell well, which now makes it rare. Clean units can go for $300–$800 today.
3. Gaming Items: Pokémon Pikachu Nintendo 64 (1999)
Bright colors, oversized design, and Pikachu’s face staring at you. This console became one of the most recognizable gaming items, with boxed versions regularly selling for $1,000 to $2,500.
4. Eye of Judgment Cards (PS3, 2007)
A forgotten experiment mixing physical cards with AR gameplay. Individual rare cards can sell for hundreds, while full rare collections push past $1,000. Back when it launched, most players ignored it completely.
5. Pokémon Illustrator Card (1998)
Originally handed out to contest winners in Japan, this card sits in a category of its own. In 2026, one sale reportedly reached around $16,000,000, turning it into one of the most extreme examples of value in gaming history.
