Superman comic sells for $2.16m! | Great Business Ideas |

A copy of the first issue of Action Comics, featuring Superman's debut, becomes the world's most expensive comic, fetching $2.16m (£1.4m). It’s the first time a comic book has broken the $2 million barrier. The issue was published in 1938 and cost just 10 cents. Connoisseurs of the comic world say this type of investment has become popular during troubled economic times because rare collectibles hold their value more reliably than property or shares.
