Numismatic collections on display in Ireland / Northern Ireland

Dear colleagues,
I am traveling to Ireland and Northern Ireland in late August. Are there good numismatic collections on display in the museums pf Dublin and Belfast?
By googling, I found that both museums have pretty good collections, especially the one in Belfast (the Ulster Museum). However, I was unable to find out online (including the websites of the museums) if any decent part of those collections is currently on display in either museum, or if they are only exhibited on special occasions?
I'd appreciate any advise, especially from locals.

I visited Dublin about 15 years ago.  One museum a coin room.  There were not a lot of coins, probably because few coins were mad in Ireland.

The National Museum in Dublin has a permanent display of coins and notes of Ireland located at Collins Barracks. It is easily accessible by public transport, and there is a car park if you are driving.

I will see if I can find out if the Ulster Museum has a display.
