Royal coat of arms of the United Kingdom The royal coat of arms of the United Kingdom, or the Royal Arms for short, is the official coat of arms of the British monarch, currently Queen Elizabeth II. These arms are used by the Queen in her official capacity as monarch of the United Kingdom. Variants of the Royal Arms are used by other members of the British royal family; and by the British government in connection with the administration and government of the country. In Scotland, there exists a separate version of the Royal Arms, a variant of which is used by the Scotland Office. The arms in banner form serve as basis for the monarch's official flag, known as the "Royal Standard".
History of the halfpenny The British halfpenny coin was worth 1/480th of a pound sterling. At first in its 700-year history it was made from silver but as the value of silver increased, the coin was made from base metals. It was finally abandoned in 1969 as part of the process of decimalising the British currency. "Halfpenny", colloquially written "ha'penny," was pronounced ; "1 ½d" was spoken as "a penny ha'penny" or "three ha'pence" .
