The euro is useful because it has simplified travel to Europe but I miss the old pre-euro currencies. To have a wallet full of romantic and exciting sounding notes made you feel like a true international traveller. I liked the French franc and the Spanish peseta and the Greek drachma of course but my absolute favourite was the Italian lira simply because you just got so many.
I agree. The paper money of other countries is colorful and pleasant to look at, and it’s a shame to lose them.
