Joe - you never asked! I could have explained most of the Dublin argot as we sat in the snug of Kehoe's - where you figured out the match-strikers! Now, for the advanced class - try asking for a "meejum an' a ball of malt"!As far as coins are concerned, the interesting thing will be to see how much slang survives the double-whammy of decimilisation and eurofication.
