Use it as a spurious excuse to travel to the Auld Sod where the Central Bank on Dame St., Dublin 2, will change it for ya into the princely sum of 8 (euro) cents. No date limit on that either. If you're going to take up Catspaw's option, on the other hand, I reckon it was highly-placed executives in the 2 biggest Irish banks that done it. That planted the damn thing in that till. Do everything advised 'cept sing 'em 'Pretty Boy Floyd' backwards as ye're doing it...
