Thanks to advanced technology, an extraordinary hologram effect was obtained on the coin, which spectacularly changes color depending on the incidence of light! Limited edition - 500 pieces.  Britannia is a very popular bouillon coin. Minted by the British mint - The Royal Mint. It is guaranteed by the British government and is a fully fledged means of payment in the UK. The first silver Britannia was struck in 1997.  This year's version was struck from 1 ounce of 999 silver. The reverse is decorated with the unchanging personification of Great Britain, which dates back to Roman times. In the Victorian era and during World War I, this image served as an anthropomorphisation of the British nation and for the propaganda purposes of Entente. The obverse is modified in every odd year of its publication.
