Original Game Boy

The original Game Boy, Nintendo's 1989 gray brick, remains the most culturally significant portable console ever, with 118.69 million units sold including the Game Boy Color. Its legendary durability was proven when a unit survived a Gulf War bombing — the charred-yet-functional console now resides in the Nintendo World Store. For investors, sealed original Game Boys command $1,000-$5,000 depending on condition, but the true goldmine is sealed first-print games. A sealed pack-in Tetris sells for $500+, while Pokémon Red or Blue can fetch $10,000-$50,000, outperforming #5's Transformers sealed figures by a factor of five at auction. The Game Boy proved portable gaming wasn't a gimmick, creating a hobby that now yields serious returns.
