Nope, I mean the old Australian Florins pre-war ones. The picture you have is for the UK Pound Coins (old ones not the new 12 sided ones).
The George V & coat of arms design was discontinued after 1936, no issue in 37.. New design in 38 was George 6 coat of arms got chubbier (earlier design more sleek but high detailing wore down easily such as emu and roo).
