Did you know that a single watermelon once sold for $6,125. In 2008, a man in Japan bought a nearly black Densuke watermelon for ¥650,000 or $6,125. The specialty fruit is only grown on the island of Hokkaido and, according to a Japanese agricultural expert in the Los Angeles Times, is crisp and hard with "a different level of sweetness" than the watermelon we're used to eating.
