Likely mintages for 2022 jubilee sovereigns?

[RDHC]

Not many new threads at the moment, so I thought I might air a question that has been in my mind for some time. I don't have any answers, except that I have a feeling - without any factual basis, I hasten to add - that even for the basic jubilee sovereign, despite all the publicity at the time, the mintage might well be less - considerably less? - than some of those for, say, the Gillick years (o.k. I know that the latter vary considerably). Of course, proof editions may have a finite, stated limit, but what about the bullion coins? Anyone care to make a stab at answering the question (assuming that I have posed it correctly in the first place, which I may well not have done)? 

Happy to be corrected on or at any point or assumption; I merely hope to stimulate some contributions from the better informed, probably because they will have handled, or at least seen the passage of, many of these coins.

In this context, as in others, I lament the fact that we no longer benefit from the contributions of Lawrence Chard. It is regrettable that, apparently, he was offended by what some one or other wrote,  and so he withdrew from the forum.
