It's possible that this is a "limited edition" that was done in multiples, but there are a couple of things that seem to mitigate against it - I have no actual knowledge one way or another, but my observations are:
a) the strange mix of "gallantry" and "campaign" medals, plus the addition of a "commemorative" at the very end. There are a whole series of jubilee and coronation medals. Why only one? Unless I've misidentified the final medal in the sequence.
b) the mounting of the medals seems a bit amateurish though the photos may betray the true quality; a good quality presentation would include, one would think, shadowboxing/insets, etc., as well as at the least captions - though perhaps there is a second frame with the names/post-nominals/descriptions which you are missing or not illustrating
c) the nameplate is non-descript; the cap badge displays and other similar things over the years usually had some kind of branding, or even corporate sponsorship - remember the Hiram Walker Highland Series prints, showing officers of Canadian highland regiments in full dress?
Maybe I'm jumping in too soon - would be interested in other opinions.
Meant to say earlier, though, that whatever it is, it is a nice collection of miniatures in its own right and should make a nice addition to your war room.
