Queen Elizabeth II returned to the public eye Wednesday after two weeks in seclusion as she recuperated from what officials called a “heavy cold,” prompting many to wonder whether the 90-year-old monarch’s reign might soon come to an end.

In the wake of a more unfortunate end to her reign, Elizabeth’s son Prince Charles is likely to inherit the throne, but the position of Great Britain’s figurehead isn’t all the current ruler would leave behind. Her personal wealth, as of April, was estimated to be a total of $84 billion, according to a report by the consultancy firm Brand Finance. Her immediate family benefits not only from the housing and services that come from their royal status, but quite a bit of untaxed income as well.

The Crown Estate: $14.8 billion

The Crown Estate, an independently-managed business belonging to the monarch for the duration of her reign, includes Regent Street, Windsor Great Park, seabed, farmland and half of the St. James’s district in London, among other retail properties. The Treasury receives its revenue surpluses, of which the queen receives a so-called “Sovereign Grant” of about 15 percent. That amount is channeled toward hospitality, administrative and security services for the royals in Buckingham Palace. Its portfolio value rose 9.7 percent to 12 billion pounds, or $14.8 billion dollars, as of June.

Racehorses, china, jewelry, Faberge eggs and more art: at least $86 million

While some of the art included in this inheritance is now part of the larger collection described above, Elizabeth II inherited 70 million pounds, or $86 million, worth of valuables after her mother Elizabeth, Duchess of York, died in March 2002.

The inheritance included pieces by Jean-Claude Monet, which would go on public display at the Buckingham Palace, as well as shares for Princes William and Harry totaling to about 14 million pounds, or $17.24 million. Elizabeth did not pay any of the U.K.’s 40 percent inheritance tax, as a law allows an exemption for estates passed from sovereign to sovereign.
