It's a fine line, to some extent. Even Balmoral and Sandringham are somewhat in trust for the Crown, although technically the Queen could sell them both, because the upkeep and security is paid for by the Civil List.
If the monarchy formally ended, the Queen would most likely surrender the stamp collection, her art and most of the family jewels. Her personal property would probably consist solely of her private money and whatever the value of Sandringham and Balmoral was assessed via an annuity. It would not be paid to her in a lump sum amount.
