The harp is a constant, the animal designs change between the denominations, though it is weird they seem to be ruled by an ancient musical instrument....
That instrument can actually be visited.

It's the King Brian Boru harp, at Trinity College in Dublin. The only Irish coin (AFAIK) that does not have the harp is the Easter Rising commem from 1966.
On Irish circulation coins issued after 2000, the harp is unfortunately the sole design for all eight coin denominations. A little dull, but well, if that is what they want ...
