Im sure they'll keep circulating. They're not gonna go in your house to replace them, or to stores. But gradually they will. And new money is gonna be printed or already has for when she dies, and then you repeat this with every king or queen that dies. Its a complete waste of ressources.
Erm...all our notes are reprinted anyway. That's why this new £50 note exists - because the old notes will cease to be legal tender (after a grace period has expired), and the new note will replace it.
My point is that when Queen Elizabeth II dies, notes (and coins) with the new monarch will be gradually introduced as part of this process. There's no additional wastage beyond the general process with which notes and coinage is changed anyway. Are you arguing that notes should not be updated at all?
That's why, for example, there are no coins with Edward VIII's portrait on them, because there was no time and/or need to introduce these as he abdicated so soon after his coronation.
You seem to be suggesting that billions of pounds worth of notes are being stored for as and when the queen dies, which is simply not the case.
So what you are saying is that they already spent that tax money? Because of someone who could very well never become king making it a total waste of tax money?
He's probably had a series of royal portraits produced, but I imagine that the cost of that is relatively small.
Edit: Apparently I was slightly wrong, and the Edward VIII's abdication did incur an amount of wastage:
The Royal Mint said:
The mint was in an advanced state of readiness – reducing machines had begun the process of miniaturising the designs ready for coins and medals. The abdication put paid to these plans and no coins of Edward VIII were ever issued in the United Kingdom.
But no, not even in that instance were countless coins molded and then melted down!
