Today the Royal Mint published the mintage figures of 2023 dated coins. From what I have seen I anticipate most of them commanding high premiums because they aren't available elsewhere but circulation, due to the 2023 definitive sets featuring a privy mark.
As usual there were no 2 Pence and 2 Pound coins minted in 2023. They can only be found in the sets with the privy mark only
The 2023 Salmon 50p has an incredible low mintage of just 200,000! dethroning the 2009 Kew Gardens as the lowest minted 50p in circulation (2nd if you include the 1992-93 EEC of just 109,000).
The 20p had only 525,000 minted last year which has made it the lowest minted 20p beating out the 2008 Gardner 20p with 11.9 million in 2008.
The Penny and 10p are tied at 600,000 minted which means both have the lowest mintage for each definitive (Excluding the alphabet 10ps)
At least the 5p and Pound coin have a respectable mintage of 32.4 million and 10.03 million between them so they would be quite easily findable once they are released into circulation.
