Secrets of Royal Family’s Hidden Billions: Property Deals, Jewels, Raunchy Novel Royalties and Palace Hideaways — But They Still Scrimp on Electricity and Food!

As Queen Elizabeth’s successor to the throne, Charles, 75, was left the bulk of the late queen’s estate completely tax-free.

The monarch’s private worth includes palaces, castles and estates worth $415 million, including Sandringham and Balmoral, world-class art, car and stamp collections, opulent jewels, cash courtesy of the Duchy of Lancaster, and more. But Charles still knows the value of a pound — last year he ordered the temperature lowered in Buckingham Palace to save on heating bills, plus he’s known to eat leftovers.
