Depends what we deem a winner, but in terms of desirability and importance yes, 100% its going to be desirable and important forever more. Its a superb design and the first sovereign of a new monarch and we shouldn’t let the madness of release days distract us from the bigger picture.
Its only in very recent years have any coins sold out in the first days / few hrs (since mid 2020) and that was due to the very weird and pumpy environment we were in. 1989, 2002, 2005, 2012, 2016 & 2017 and everything in between took days if not weeks (and probably months on the early ones). These will all be sold out soon enough if that is what some measure success by.
In terms of mintages these (the 5 and 2 anyway) are low for proof coronation / first of a monarch sovereign sets if you look at anything from Edward VII 1902 proof set onwards. Regardless of what comes, this set is as important as any sovereign set that marked a new monarch and also rarer than most, with the odd exception (1953 for example). Arguably for Sovereign collectors, particularly type collectors this is the most significant and important release in 85yrs, since George VI.
1902 5 coin proof set 8,000 ish sets
1911 5 coin proof set - 2,800 ish sets
1937 5 coin proof set - 5,001 sets
1953 5 coin proof set - 3 or 4 sets
2022 5 coin proof set (KCIII) - 1200 sets (less than 2000 2 Sovereigns in total)
as something to think about, even the 1839 Una has reported mintage of 400 and I doubt that fully accounts for the extra’s struck in the years following 1839.
i grade so I've picked up a few sets todays where I could, i’ll put a 5 coin 70 set together and then move the rest on, a  profit would be nice but not essential.
These are superb and i think once im hand collectors will be very reluctant to let them go.

Thank you to Backyard Bullion and Silver Mike for their posts. They both summarised what I was feeling about this release. 
 
It’s been a long day, got 622 in the queue and was in and out by 9.03am. Got what I wanted, although it turns out the rush wasn’t needed today. It’s been fun reading everyone’s reactions. May we share the spoils in up to 12 weeks.

Thank you for such a detailed and considered response. I think you hit the nail on the head here: "in terms of desirability and importance yes, 100% its going to be desirable and important forever more. Its a superb design and the first sovereign of a new monarch and we shouldn’t let the madness of release days distract us from the bigger picture." 👏
I'll be thrilled when mine arrives (all being well with the infamous Llantrisant QC!) and can't wait to see it up close... even if I have to squint and imagine that JC included a daff with the other floral symbols! 😝

When you put things like that it's proof in the pudding/mintges 
New to proofs and the like past few years.
Buy and HODL with little downside 
Watch and enjoy as and when.thimgs are sold, flipped, graded and sold. 
Enjoy the journey, little downside risk, fingers crossed  hopefully

1911 5 coin proof set - 2,800 ish sets
1937 5 coin proof set - 5,001 sets
1953 5 coin proof set - 3 or 4 sets
2022 5 coin proof set (KCIII) - 1200 sets (less than 2000 2 Sovereigns in total)
as something to think about, even the 1839 Una has reported mintage of 400 and I doubt that fully accounts for the extra’s struck in the years following 1839.
i grade so I've picked up a few sets todays where I could, i’ll put a 5 coin 70 set together and then move the rest on, a  profit would be nice but not essential.
These are superb and i think once im hand collectors will be very reluctant to let them go.

Depends what we deem a winner, but in terms of desirability and importance yes, 100% its going to be desirable and important forever more. Its a superb design and the first sovereign of a new monarch and we shouldn’t let the madness of release days distract us from the bigger picture.
Its only in very recent years have any coins sold out in the first days / few hrs (since mid 2020) and that was due to the very weird and pumpy environment we were in. 1989, 2002, 2005, 2012, 2016 & 2017 and everything in between took days if not weeks (and probably months on the early ones). These will all be sold out soon enough if that is what some measure success by.
In terms of mintages these (the 5 and 2 anyway) are low for proof coronation / first of a monarch sovereign sets if you look at anything from Edward VII 1902 proof set onwards. Regardless of what comes, this set is as important as any sovereign set that marked a new monarch and also rarer than most, with the odd exception (1953 for example). Arguably for Sovereign collectors, particularly type collectors this is the most significant and important release in 85yrs, since George VI.

The last time there was a King wearing a crown on UK coinage was... in the 17th century.  And the last time there was a King even wearing a laurel wreath on UK coinage was in the 1820s.
So Charles is merely keeping with 'recent' tradition 🙂

The exact same scenario as the 2022 proof. Didn't sell out rapidly. Everyone got fearful and thought I will just wait because they did not see an instant sell out. The Queen croaked it and what do you know everybody flocked to get one.
If people don't see an instant sell out they wait and when it eventually sells out they get FOMO. 
By the time the coronation comes around you will be sitting pretty with these. Every time RM have hiked price or mintage a few more question this. Those who sat on the side will pay the inflated price. IMO
