They are really nice designs, I got the 2023 BU set just to see them. I don't tend to go for the sets anymore but these seemed especially good.
The left ~third having the three interlocking “C” shapes (Charles Third), which itself is a callback to the double-locked “C”s of Charles II. (I know there's exceptions for CII maundy money).
Then a good mix of wildlife & plants from across the country making the bulk of the design. A good way to recognise Charles' love of the natural world. He's been speaking about the importance of the environment for decades so it's nice to have a personal touch for him.
A cool blend of historic artwork & the natural world.
I much prefer it over the shield puzzle of the 2008 redesign of the coinage. Not that it was a bad design per se, it's always a cool trivia fact to spring on people, but it just never quite felt right. Idk, can't describe it.
Hopefully, they'll all wind up circulating eventually. 🙂
