I was under impression that those will be loose unc coins, and will be technically issued for circulation.
Extremely unlikely. As the Mint is now producing commemoratives that are explicitly stated as not being issued for circulation, it’s almost a dead cert that these won’t be. The 2009 ones weren’t. Of the 10 coins, only the D-Day one is reaching a (fairly) significant anniversary next year of the event it commemorates (75 years). For that reason, I’d like to see that circulate but it won’t.
Andyg has a point there... the perceived rarity of a coin is partly because of the fact it does/did circulate but in small numbers. It’s possible but extremely unlikely to find a 2009 Kew Gardens in change, but it’s desirable precisely because it circulated. There are a number of coins this year that aren’t being issued for circulation but as this has already been confirmed, those who want them will be buying them now in the packs. Kew was announced long after the event when it was too late for most people, hence the mad scramble and the silly prices for any sets it appeared in.
There might be some interest in this new set because of the Kew Gardens coin (and perhaps the D-Day one) - but the likely high issue price of this might mean it’s still cheaper to find any 2009 set with it in, or even the single (genuine) coin.
Even for me, this new set is much less desirable than the 2009 one. That set was irresistible as it had the four large-size only designs issued on the smaller coin for the first time, and all paired with the Rank-Broadley portrait. In the case of the Ring-of-hands one, it was on frosted proof for the first time (though disappointingly altered to add visible arms). This new set still has the D-Day coin from the large coin era, but been there, done that, and the fact that they’re now all paired with the Jody Clark portrait instead of the Rank-Broadley isn’t something to write home about.
Contradicting what I said in a previous post I know...
