If I could be bothered to look for statistics, I think I would find that over 65s have more disposable income than some of the other groups.
If there are fewer "collectors" for new issues, then I think mints will issue fewer coins, so that part of the market will remain in balance.
"News issues" are a fairly recent development in the UK since about 1970, although slightly earlier in the USA.
Many, if not most, "real" collectors are more interested in earlier coins which were mainly made for circulation, rather than the somewhat artificial "made for collectors" market.
I think many "young" people currently obesssing about NFTs and crypto, will move on to something different once the current bubble-like hysteria has died away, and reality reasserts itself.
Although proof sovereigns are nice to have, I get more excited when I get to see ancient coins, hammered coins, milled coins, including rarities, but also some quite common coins if they are in great condition.
Sure, there might be a price drop in some recent issues, but why worry about it if you are a real collector, not simply buying new issue coins because you think they will be a good investment.
In fact, if prices drop, you will be able to buy more coins for a lower outlay.

From the coin dealers I've been buying from, they say that coins have been flying off the shelf, the numismatic market seems strong now and they are struggling to keep up with demand.
I'm talking proper numismatic coins here, medieval coinage through to the Victorian era. So we're not talking modern proofs and BU coins, I can't speak at how those are doing.
