Marshall Mathers is better known as the multi-platinum-selling American, rapper and producer Eminem. As someone who’s been working hard to entertain all of us for the better part of almost three decades now, Em has become one of the most consistently highest-paid entertainers in the entire world with an estimated net worth said to be in the $230 Million range according to sites like Celebrity Net Worth. How is he worth so much? Well, it’s not for a lack of trying to spend it. Yes, Em has all the necessities like his $1.4 Million home base in his native state of Michigan where he’s lived for over twenty years. And as a self-confessed collector, Em has also spent no small-sum of his fortune on cars capable of reaching break-neck speeds but he’s also willing to drop a small fortune on some truly geek-tacular collectibles like the very first appearance of Spider-Man worth $1 Million.
