To mark the centenary of the Proclamation of the Irish Republic the Central Bank of Ireland is also issuing limited edition commemorative coins in gold and silver. These striking collector coins depict a representation of Hibernia with key words and phrases from the Proclamation. These coins are issued with certificates of authenticity and a document tracing the history of this momentous occasion. The coins were designed by Michael Guilfoyle who has over thirty years experience as a numismatic artist. He has designed coins and medals for countries throughout the world and is best known to coin collectors for his coin designs for Ireland, including those commemorating Sir William Rowan Hamilton, Skellig Michael and Saint Brendan. The €100 gold proof coin contains a half ounce of fine gold, struck to the finest proof quality. The larger diameter of the coin allows the detail of the design to be appreciated at its best.
