The issuing collecting of commemorative medallions has a long history. Many Australian die-sinkers produced these as well as buttons, badges, medals and the like. Here is a medallion struck to commemorate Stokes and Sons centenary. It includes the first likeness of Thomas Stokes I have found!
Perfection Plate, a silverware firm, produced buttons for the military in 1942.
I couldn’t resist this quirky offering from the company in 1954.
