Notes
The Memorial Plaque was issued after the First World War to the next-of-kin of all British and Empire service personnel who were killed as a result of the war.
The plaques (which could be described as large plaquettes) about 4.75 inches (120 mm) in diameter, were cast in bronze, and came to be known as the "Dead Man’s Penny", because of the similarity in appearance to the much smaller penny coin which itself had a diameter of only 1.215 inches (30.9 mm). 1,355,000 plaques were issued, which used a total of 450 tons of bronze, and continued to be issued into the 1930s to commemorate people who died as a consequence of the war.
