You asked for a clue.
the answers you received are correct.
what you have are just circulation coins some of them are not in good shape for example the "green stuff" on a coin is "death to a coin".

here is the clue
William Morris Hughes
Stanley Melbourne Bruce
James Scullin
Joseph Lyons
Earle Page
Robert Menzies
Arthur Fadden
John Curtin
