Queen Elizabeth II has been depicted on British banknotes and coins for decades. Her portrait also has been featured on currencies in dozens of other places around the world, in a reminder of the British empire’s colonial reach.

So what happens next after her death this week? It will take time for the United Kingdom, Canada, Australia, New Zealand and other countries to swap out the monarchs on their money.

But that doesn’t mean the bills don’t work — they do.

Here’s a look at what is next for the paper cash featuring the late queen:

SWITCHING MONARCHS

The queen’s portrait on British notes and coins is expected to be replaced by a likeness of the new King Charles III, but it won’t be immediate.

“Current banknotes featuring the image of Her Majesty The Queen will continue to be legal tender,” the Bank of England said. An announcement on existing paper money issued by the U.K.’s central bank will be made after the official 10-day mourning period has ended, it said.

The Royal Mint, which is the official maker of British coins, said all coins with her portrait “remain legal tender and in circulation,” with more information to come later.

“As we respect this period of respectful mourning, we continue to strike coins as usual,” the Royal Mint said on its website.
