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.

I was going to buy 1 full sovereign and the 4 box set...
Ended up with 
2 × 4 box set 
1 × 3 box set 
2 × full sovereigns 
1× half sovereign 
Tempted for the 5 box ...but wife will go mad lol

I wonder why...😂

Managed to get through to customer services. Set sold immediately and my payments will be returned. C’est la vie. 

That’s to much hassle. I already have a headache. 😂😂

Gee that was quick delivery.
My postie is normally still in bed resting his throwing arm.

I’ll give you a quid-each for a Potter 50p 

I'm not tied by contractual matters like Lawrence is so i'll tell you....
Its the Dianne Abbott £7.00 coin... it has a denomination of £7.00 and worth £0.11p ,,,, you get 857 of them per £ and 342 of them make A SHEKEL... 
She can count to potato....

Always wanted one of these, but the wife would spend a fortune on fuses...

Unless you are talking about the gold 50p, the silvers are not all that expensive.  Just get off the fence, open your wallet, and support your local RM!  They will appreciate it immensely as they package your damaged coin for delivery in January!

I think these RM 1oz gold bullion coins could be a better value option to buy going forward, over their significantly dearer new release 1oz gold proofs
The second series Queens beasts are fabulous use of the microdots engraving as @GoldDiggerDave brought up a few weeks back elsewhere   
Looks like this series will continue in the same vein 

yes and the web site appears to have frozen  

Those comments are better than fully paid up members who never buy or trade who just post conspiracy theory threads and wear silly tin foil hats ..

Full metal geek out 

Yes well done and thanks 

Cheers, and likewise thanks for your contributions too. It’s what makes all this poking around fun and worth it - to have so many people here appreciating and geeking out over everything. ☺️

Yes well done and thanks

How do you know this? Speak up! 😀
WHAT?! 🫣

DESIGN OF THE COINS
6. The design of the said five pound, two pound, sovereign, half-sovereign and quarter-sovereign gold coins shall be as follows:
‘For the obverse impression Our effigy with the inscription “· CHARLES III · DEI · GRA · REX · FID · DEF ”, and for the reverse a depiction of Our Royal Arms and the date of the year. The coin shall have either a plain or grained edge.’

https://www.thegazette.co.uk/notice/4170151

Many people may not realize this, but where QE II’s Royal Cypher and Coat of Arms used a depiction of St. Edward’s Crown, KC III’s Cypher (which was revealed a few weeks ago) uses the Tudor Crown. This is expected to be used on the Royal Coat of Arms for the King’s reign.
Hence the 2023 Sovereign will have this very subtle but important change from the 2022 Sovereign.

Two special reverse sovereigns in a row, why ambassador you are really spoiling us 😀

Just also found out today there is a new KCIII NGC label available for me to use! 

Can I just take this moment to once again thank @westminstrel for their illustrious info-digging and insights from the other side of the world! You really do seem to have your finger on the pulse on these sorts of things.

According to Atkinson's I should be  taking up this "Opportunity of a lifetime "   This is obviously stock clearance dressed up .  "Don't Miss out- Get yours Now! " indeed.
