two and a half millenia of
world and Irish coinage

Say "Hi!" to Num-NI!

The Numismatic Society of Ireland (Northern Branch) first met in 1963 as a group of local enthusiasts and scholars to share their interest in the history and art of world coinage. For over 50 years our Society has been promoting the hobby and the study of coins locally and across Ireland and the UK. We meet regularly to exchange news, display recent acquisitions and raise awareness of emerging market trends, discoveries and opportunities. JOIN US to find out for yourself the joy and challenge of coin collecting and studying! Young members with an interest in coins and medals are particularly welcome, and will benefit a lot from our expertise and support! 

FREE Coin Identification!

Avail yourself of our immense expertise by submitting photographs of both sides of your unidentified coin, medal or token, ideally alongside a ruler, to get full details on what it is and some useful references. We DO NOT BUY OR SELL COINS, neither do we provide grading and evaluation services, but you can always contact COIN DEALERS in Belfast who will be happy to advise on the value and market prices. 

Pick of the Week!

Coming Soon!

This ill-shaped coin (c/o Coin-Tiki), depicting the horned river god Rhine, was struck under Postumus, the first Gallic Emperor, to celebrate restitution of peace at the western frontiers. In 258-261 AD, Irish King Cormac Ulfada, restorer of the Tara palace and lord of epic Finn Mac Cool, invaded Wales, but was driven out by the Romans. In 263AD, Postumus had come to Britain with his Gallic Army to deal with the counter-offensive by Irish, Picts and Saxons, and united Britain with Gallic Empire.
