Yes, commemorative as in "first year of reign". Crowns were not produced for general currency purposes after 1901 (some might argue for the 1902) and were either issued as specimen proofs (1927), in response to 'coinie enthusiasm' (wreaths), commemorating a jubilee (1935) or special event (1951, 1960, 1965), or commemorating the first year of a reign (1937, 1953).
Sorry, I don't understand your point?
