I could be wrong, but I believe you have a medal or token, not a coin. Mary was George's wife, not his co-ruler in the tradition of William and Mary back in the 17th Century. If it is a coin, it's from a British Commonwealth member or colony, not England. Once again, a look at the reverse, and a mention of the size, would be very useful in trying to ID it.
Cannot really read all the tiny characters left and right of the Irish harp, but does it actually say NUERNBERG on the right? If yes, that could indicate that the medal was made in Nürnberg (Bavaria). Maybe it commemorates some visit of the royal couple to Germany? Just guessing here ... Christian
More likely an anniversary of the visit. To me the piece does not have the look or feel of a 17th Century strike.
King George V's reign was from 1910 to 1936.Queen Mary was his consort & Queen Elizabeth II's grandmother. Aidan.
From what I can learn,George V an Queen Mary were honored with commemorative coins just about every where they visited from the coronation until 1936.This is one of them although I can't find this exact one...yet
Mikjo0,there were very few commemorative coins commemorating King George V.This is a medalette which has had the lug broken off.The only countries that issued commemorative coins was Great Britain & Canada,which commemorates King George V's Silver Jubilee (1935).This medalette can be dated from 1911-14.
