Densuke Black Watermelon ($6,100)
A very rare type of melon that is grown only on Hokkaido Island in Japan; with the annual collection of well under 100 watermelons. The price listed is for a 17-pound melon and is considered unique for a crispiness and hardness.
Yubari King Melons ($22,872)
While they look an awful lot like the cantaloupes you can find at your local supermarket, these melons have a unique proportion and sweetness that are sold for high dollar marks at auctions. There were only approximately 100 total melons in 2008 with one being sold for about $23,000 to someone who owned a seafood restaurant and souvenir store.
