An 8-year-old boy stumbled across something both disgusting and lucrative while strolling the beach in his native Great Britain.

Charlie Naysmith discovered an unknown object that looked like a yellowish beige rock with a waxy finish, according to the Daily Echo newspaper. The "rock" turned out not to be a rock at all, but instead, a piece of ambergris, a substance expelled by sperm whales. Ambergris is actually in demand with perfume makers as it helps prolong the scent of perfume, which is why a pound of it sells for as much as $10,000.

Naysmith's piece of cetacean upchuck has been estimated to be worth as much as $63,000, but, according to his dad, Alex Naysmith, they are still researching the product.
