demonboy,
Dei gratia regina means : "Elizabeth the Second, by the Grace of God Queen."
The same like D.G. REGINA,but this time this is an abbreviation of the expression.
1953-1964 (Laureate effigy)had the obverse like the one you have
1965-1978 ( Queen with Tiara,that is a crown)had the new version of the Queen portret with "Elizabeth II D.G.REGINA"
1979-1989 ( modified Tiara)is the same obverse but made smaller to standardize,to make the effigy proportional to the diameter of the coin
1990-2003 changed the Queen's portret again,more mature ( a book I have it says this was the first design made by a canadian,doesn't give the name of the designer though)
2003 to today,Queen changed again,this time without crown and naturally a little bit more mature.
