Both Alan’s
badges are good examples to study, there is another die where a void exists at 6 o’clock but these are fully die struck in appearance from the reverse rather than Alan’s types which appear almost semi-die cast. It’s hokum that this void must be present for the badge to be genuine.
Other ranks badges are found on sliders, often the early post 1902 long slider, sometimes these are shortened or cut down like my badge below. From memory every or almost every slider on these badges has a crimp mark.
The fully die cast badges with the void on loops sold by many dealers as cap badges are in fact
collar.
