Let’s be honest, it’s hard enough to get your hands on a convention exclusive, a hot new Funko Pop!, or a retailer-exclusive Star Wars The Black Series figure — The idea of owning something as rare (and expensive) as a copy of “Fantastic Four No. 1” or the legendary Alpha Black Lotus Magic: The Gathering card is almost laughable. But a company called Mythic Markets has created a new way for fans to own the one-in-a-million, nerdy collector’s items that sell for a small fortune… or, rather, to own part of them.

Mythic Markets offers fans shares in these valuable items, and those shares are available to buy, sell, and trade on the Mythic Markets platform. Usually, the items are broken down into about 1,000-2,000 shares, which makes the price far more accessible. Few people can invest $50,000 in an A-grade Metroid cartridge, but how about $25 to own a share of it? And, as in any stock market, you may be able to sell that share at a higher price if the value of the cartridge goes up. (Mythic Markets determines the value of its stock via peer-to-peer bid and ask activity.)
