I got this coin in my change about 20 years ago in an Irish bar. I now who Joseph Devlin is but I dont know whether this is a coin or a medal or badge. I cannot find this coin/medal anywhere on the internet so would appreciate some advice. it has a milled edge and is 25mm diameter and has "A NATION ONCE AGAIN " on it. Any ideas anybody. It has an image of a harp on the reverse .
