Heads and Tales is the name of a newly opened exhibition at the National Museum of Ireland at Collins Barracks. The exhibition traces 1,000 years of Irish coins and currency. With the arrival of the euro it might be interesting to put next year's currency change in context. The free exhibition is open on Tuesday to Saturday from 10 a.m. until 5 p.m. and on Sundays from 2 p.m. to 5 p.m.
