You probably tossed some video games the moment a newer console came along. Old cartridges disappeared into boxes, scratched discs went in the trash, and games that seemed outdated were practically impossible to give away. Nobody was thinking about what collectors might pay for them decades later.
Today, certain video games have become serious collectibles, especially rare releases, limited print runs,s and copies that still have their original packaging. Some have sold for hundreds or even thousands of dollars, turning forgotten games into surprisingly valuable pieces of gaming history.
1. Stadium Events Could Be Sitting in an Old Nintendo Box

Most people who owned Stadium Events in the 1980s had no idea they were holding one of the rarest NES releases ever made. Nintendo recalled the game and replaced it with World Class Track Meet, leaving very few surviving copies. A sealed NTSC copy famously sold for $41,300, while current collector guides put sealed examples far higher.
2. Little Samson Was Easy to Miss on the NES

Released near the end of the NES’s life, Little Samson never became a blockbuster. Its relatively small print run is exactly what makes it interesting today. Complete copies can sell for $2,000 or more, while high-grade sealed examples can reach dramatically higher prices.
3. A Copy of Rule of Rose Could Be Worth Hundreds

The PS2 had an enormous library, but some of its later releases were produced in relatively small numbers. Rule of Rose, a 2006 survival-horror game, has become one of the standout examples. Current collector estimates put complete copies around $485 to $1,150+, depending heavily on condition.
4. Nintendo World Championships Is Basically a Video Game Holy Grail

Only 116 original Nintendo World Championships cartridges were produced for Nintendo’s 1990 competition, making this one of the most extreme examples of a game that almost nobody could casually own. A CGC-certified cartridge sold for $78,080 in 2024, while another graded copy previously reached $180,000.
5. Panzer Dragoon Saga Became a Sega Saturn Monster

Sega Saturn games weren’t exactly flying off American shelves, and Panzer Dragoon Saga had a particularly limited release. That scarcity eventually turned the RPG into one of the Saturn’s most expensive games, with current estimates putting complete copies around $785 to $1,538.

6. Suikoden II Is One PS1 Disc You Shouldn’t Toss

By the late 1990s, nobody expected a PlayStation RPG to become a serious collectible. Suikoden II has done exactly that. Black-label complete copies are currently selling around $420 to $520, with the original manual and packaging playing a major role in the price.
7. Hagane: The Final Conflict Never Had a Huge Audience

Released for the SNES in 1994, Hagane: The Final Conflict was never one of Nintendo’s household-name games. Its limited distribution, however, made it increasingly difficult for collectors to find. Complete examples are now estimated around $800 to $1,500, with graded copies potentially worth considerably more.
8. A Sealed Super Mario Bros. Became a $3 Million Collectible

Nobody needs an introduction to Super Mario Bros., but the rarest sealed copies are another story. In June 2026, Heritage Auctions sold the highest-graded copy of the earliest confirmed sealed edition for a record $3 million. Obviously, an ordinary used cartridge isn’t remotely worth that amount, but the sale shows just how extreme the market can become for exceptional copies.

9. Klonoa: Door to Phantomile Became a Quiet PS1 Favorite

Unlike Final Fantasy or Metal Gear Solid, Klonoa wasn’t exactly dominating conversations in the 1990s. Its relative obscurity and limited availability helped turn the original PS1 release into a collector favorite. Black-label complete copies are currently estimated around $340 to $410.
10. Cheetahmen II Was Almost a Forgotten NES Disaster

Cheetahmen II has one of those bizarre histories collectors love. The game was released in extremely limited numbers after its publisher went bankrupt, leaving surviving cartridges unusually scarce. Current price guides put complete examples around $5,000, while sealed copies can be worth considerably more.
11. Persona 2: Eternal Punishment Became a PS1 Sleeper Hit

The original PlayStation release of Persona 2: Eternal Punishment was never a massive seller in North America. Years later, collectors began paying close attention to the black-label version. Complete copies currently fall around $240 to $310, making it one of those games that could have looked completely ordinary in a box of old PS1 discs.
12. The Legend of Zelda: A Link to the Past Still Has Serious Collector Appeal

Millions of people remember A Link to the Past, which makes its collector value particularly interesting. The ordinary cartridge isn’t a fortune, but complete, professionally graded copies can sell for thousands. One CGC 9.6 complete-in-box example sold for $2,229, showing how much packaging and condition can change the equation.
