Whos's image appears on UK (and some Commonwealth coinage and notes) if the monarch is not 18 and a regent is in place?

[Oddjob]

So, whilst the UK has a Regency Act that has been updated over the centuries to take into account various situations regarding succession to English throne, if a minor acceded the throne but could not be be crowned till they were 18 years old, who's image would appear on the coinage of the UK and other countries???...The "to be" crowned minor, the Regent or would the prior monarch's image remain on the coins, notes and stamps until such time as the to be crowned minor became 18 and legally accedes the throne?

Chances of this happening (with Charles and William next in line and unlikely to drop of the peg anytime soon) appear low to nil, but just a question that came to mind when reading another thread re Charles on the Soc coin one day.

Probably the young monarch.  The most recent example, I think, was Edward VI in the 16th century who I think died while still a teenager having reigned for about six years.

Before that you have to go back to Edward V I think maybe, without looking it up?

I think you are correct @Stuntman Edward VI (1537- 1553) reigned 1547- 1553 before his death aged 15 and his reign overseen by a Regency Council.   Here he is, represented on the third period coinage: 

And this document outlines all three periods of his coinage.

Also note that Some posthumous Henry VIII coinage was issued alongside Edward VI coinage, the document also explains this.
