Free circulation of Irish pound alongside British pound

[Presidente 0]

Hi everybody! I'm new in the forum, I'm from Italy and I'd like to begin a new collection of British coins at the moment from King Edward VII coinage. I know that British Crown Dependencies coins are not legal tender in the UK as well as Falkland, St. Helena, Gibraltar and other ex colonies (Nigeria, Fiji etc.) ones but regurarly they enter in Great Britain's circulation as they have the same diameter, weight and composition of the british pound coins. What I want to know, instead, is if Irish pound coins were legal tender in UK because I red that british ones were normally accepted in Ireland (were also british coins legal tender in Ireland?) at least until 1979, the year in wich parity between Irish and British pound was broken.  

Thank you for your competent answers.

Not legal tender, but widely seen in circulation in British cities with large Irish populations. For some time the UK pound traded higher than the Irish Punt so Irish shops and pubs were happy to accept them at face value. I traveled a lot to Dublin on business and my pub of choice would let me run up a tab so that I generated a sum large enough to apply the exchange rate to.

Thank you very much, so only british coins could circulate throughout colonies and in Ireland and not local issues and Irish pound

In Tudor times it was illegal for Irish coinage to circulate in England and Wales because the coinage was struck to a lower standard. Consequently English coins traded at a premium to Irish in Ireland.
