I want to know the answer to the following question:
How much is the worth of the British Crown Estate?
All the background I'm provided with is that "The Royal Collection, which includes thousands of historic works of art and the Crown Jewels, is not owned by the Queen personally but is held in trust, as are her official residences, such as Buckingham Palace and Windsor Castle, and the Duchy of Lancaster, a property portfolio valued in 2014 at £442 million.". Is that enough to answer the question?
