Location: Three Islands in the Chesapeake Bay, Maryland
Purchased: Unknown
Current Value: $30 million*

There is a fierce debate over whether Paul Tudor Jones made these islands, or whether nature made them and the billionaire tycoon just got lucky. Either way, these Chesapeake Bay paradisos are beautiful, and they undeniably spell out “PTJ.” Jones bought them to add to his 3,000-acre wildlife preserve, which he’s owned in Maryland for years. 

The islands are part of Tudor Farms. They are located away from the main estate, though nearby enough that Jones and his family can visit. Jones has kept his islands pretty private, and satellite photos reveal all that is known about them so far.
