Royal Tudor Beasts Monarch's Head

One thing has occurred to me about the Royal Tudor Beasts series. The series started with the Seymour Panther, issued in proof but not BU. This was followed by the Lion of England and the Yale of Beaufort, in both proof and BU versions. All issues so far have Queen Elizabeth's head on the obverse. Presumably, future issues will bear King Charles' head and this may mean that the proof and BU versions of the Seymour Panther could bear the heads of different monarchs.

I believe that they still use the portrait of a deceased Monarch for a year, so it depends on how quickly they release them. But I don’t personally see an issue with having different monarch heads.

I don't see it as an issue, but it will be unusual to see, essentially, the same coin with different heads.

My understanding The head of monarch will stay until end of year the Tudor set has a few years left to run, so should be a change next year same goes for the monarch set
