Americans: "Oh no, we couldn't possibly replace Andrew Jackson with Harriet Tubman on the $20; what kind of precedent would it set if we just started changing the picture on our money?"

Australians:

@mark I mean, that's the tails side of the coin, they make new versions regularly but the heads side basically never changes until the monarch does, except to the more true to life (though if were Elizabeth I'd have prevailed on the Aussie mint to keep the original profile) just like US money.

Basically this is no different than US state quarters except more whimsical.

Still, even the "face" side of the bank notes can change.

Canada's $10 notes went
1954 - Queen Elizabeth II / Mount Burgess
1969 - John A McDonald / a giant plastic factory
1986 - John A McDonald / an osprey
2001 - John A McDonald / the national war memorial
2011 - John A McDonald / a train going through the Rockies
2018 - Viola Desmond / the national human rights museum

@jasonp @mark
They haven't yet released the rest of the bank notes in the 2018 series, but while the $20 will just replace QE II who was on all the $20s from 1954 to 2011 with King Charles III, the $5 will replace Wilfred Laurier, who was on the $5s from the 1969 to 2011 series, with another non-royal and non-prime minister person.

No monarch on Scottish notes, but we do have some nice pictures of animals.

@HighlandLawyer

This is probably a dumb question, but are those notes only accepted in Scotland, or could one spend them in, say, London? Can a note from England be used in Edinburgh? I assume those are both the case, but are the notes somehow filtered out by the banks and sent back to their home countries periodically? (They're beautiful notes by the way.)

@VirginiaHolloway @HighlandLawyer They're legal tender throughout the UK (England, Wales, NI as well as Scotland). You see a fair amount of Bank of England notes in Scotland, not many Scottish notes in England, so the banks probably do send them back (some places in England refuse Scottish £20notes because they don't see enough of them to recognise fakes).

@shark_hat @VirginiaHolloway @HighlandLawyer
My understanding of Scottish notes is that once in the banking system in England they will get repatriated to Scotland. So if a business receives a Scottish note and then banks it then note will not go back into general circulation in England.

I am sure I saw this on a telly doc many years ago.

@VirginiaHolloway @HighlandLawyer technically you can spend them in England, although sometimes people refuse to take them, but this seems to happen less often than it used to. London is not so much of a bother, you are more likely to get problems in rural areas. Occasionally supermarket self-service tills are not set up to recognise them. It's also compounded by the fact that Scotland has in fact *three* different note issuing banks.
