I had a good look at this image in the early hours of this morning and I noticed that the medallion does not show the usual ‘AB’ or ‘A’ initials. But instead, had the initials ‘AR, instead. Anne was a queen consort and not a queen regnant wasn’t she?
Well no. Anne was the only queen consort to be crowned with Saint Edwards crown (Which is reserved solely for the ruling monarch.) Making her a monarch too and means she was able to use the Initials ‘AR.’ Henry never crowned another queen after Anne died.
