My collection of police name badges from Australian and the United States. The three light blue on the left are from the New South Wales Police in Australia, the two dark blue in the middle are from Queensland Police in Australia, the three dark blue on the right are from the Victoria Police in Australia. The thin black one is an old one from the New York City Police, and the bottom two are from the Victoria Prison Service in Australia.

(The names have been edited out to protect the officers who may have worn these badges.)
