A nice thread, Darrell, thanks. (And, no, rest easy, I'll NOT drag this off into the various Durbar Medals! You are safe.) Just one more datapoint, though, the 1911 Coronation with clasp "Delhi" for those few Indian Army men (only non-Europeans, sorry) who were at both events. This one is named to 221 Lance-Naick Gurbhaji, 41st Dogra Regiment (Durbar roll, p. 456). Just 134 of this clasp were awarded. There was no standard method of attaching these loose clasps, and it was all up to the inventiveness of the regimental blacksmith.
