It very much depends on WHO you are selling to. Outside of Ireland the .com works. Inside of Ireland .IE is much more likely to be used and it's currently available to register for 5 EURO. While the .ie is available I can't see your domain having much value unless you BUILD something like an Irish souvenir shop for Irish-American tourists. I could not find any companies in Ireland, U.K. or U.S. and A. called Ireland World and pretty much every extension with that name is AVAILABLE to register. So for me it only works if you build something otherwise I concur and wholeheartedly AGREE with
@damance and
@jhm.
I like that your name expires on 15 April next year because PADDY'S DAY is 17 March so you may consider to build a Paddy's Day store, make some AD REVENUE even parking ads and see if it's worthwhile holding onto your name or letting it go. In any case you're going to need to get proactive if you want to make some money from this one. Some members will like this one because it's an aged name first registered at least as far back as 2004 which gives 17 years of history and many DNS changes. At least that means other people had ideas on your name so you're not the gazelle at the river!
If you decide to go with a for sale banner I think that you'll be waiting not just for a very long time but perhaps FOREVER.
