Right from the start fundraising buttons were intended for collecting, and people did! Stories appeared in newspapers about these collectors. Sometimes mothers passed on their war time to their children. Members of the Patrick family (manufacturers of the buttons) built up impressive collections.
From an article in The Weekly Times on 16th march 1929:
“Button days are fairly numerous -hundreds have been held in Australia since the “war series” began, and collections of the buttons sold for war funds and charities have no lack of variety in their field. Buttons of this class, of course, are much less interesting, generally, than military buttons, though many of them are attractive to the eye. Those of the war period are becoming
scarce, at least some of them are, but may have no special value.”
The writer may have been surprised at the value of fund-raising buttons now!
