A long time ago (yes, I know, I’m old) people concluded emails or postings on forums with “Just my 2 cents”. When the euro was introduced, I saw lots of postings with “just my 2 eurocents” or something along that line.
Because of the incovenience the 1 and 2 eurocent coins (they are small and you need lots of them in a store), there are places where they don’t have them anymore, and bills are rounded to the nearest 5 cents.
From 2 cents, to 2 eurocents (=4.41 cents), to 5 eurocents (=11.01 cents). Who says the euro does not make things more expensive?
