"Federal Reserve Board staff estimate that over $950 billion in U.S. dollar banknotes were held by foreigners at the end of the first quarter of 2021, roughly half of total U.S. dollar banknotes outstanding."

Is there massive, perfect counterfeiting of existing banknotes?
Another example of physical savings in fiat paper being demonetized away by the state.
This is the reason why people joke about storing money in your mattress. You aren't supposed to do it.
Cash is useful and powerful, so it benefits bankers and politicians to render stockpiles useless periodically.
Imagine it as if you are the government and acting as a dairy farmer and your cows are constantly fleeing onto private land. You can't get those cows back, instead you breed new cows. Since no cows return from the private lands and there is a constant stream of escaping cows, private lands are being flooded by cows. People complain about the government printing too many cows, devaluing the value of their existing cows.
You can see, this whole scheme is just a very backwards implemented debt jubilee in an environment where an actual debt jubilee would lead to pitchforks coming from the rich.
You can see, car analogies are bad enough.
As mentioned in the article, these notes can be exchanged at a bank or post office. Those out of circulation can be exchanged at the BoE.
The US hasn't felt the need to enact that measure even with things like the supposed North Korean "superdollars".
It's routine, it's happened to 13 notes since 1990: https://en.wikipedia.org/wiki/Bank_of_England_%C2%A320_note
However this has a lot more to do with the supply of oil and gas than the number of banknotes in circulation.
I guess these days it's kind of an expression of strength that the US has the resources to hunt down and stop counterfeiters, and pursue them through the world's financial systems if necessary.
Meanwhile, given that the UK is reportedly bringing back imperial measures [1], they will probably do something silly like deprecate another set of existing coinage and bring back shillings.

Banks usually send old notes back to the Fed when they are found. They will notice an increase in old notes being returned and investigate as well.
So you might get away with this for a short amount of time.

Suppose I use 1 stone, 12 pounds and 10 ounces in a (large) ratatouille. What weight of tomatoes do I have left?
Nah: imperial isn't coming back. The big food market in the centre of the city sells small fruit and veg in plastic bowls 'a pound a bowl' is the tarrif and the quantity in the bowl changes according to price. Larger items (cauliflowers) are priced typically by number so 2 for £1.50 or whatever.
I think that works out to 9 pounds, 10 schillings, and like 3 pence however for the tomatoes.
You can have imperial without the stone though.
