Wow, I once saw one of those, my Grandmother used to keep them! :D
However, that's a pretty nice and interesting site! Thanks!
Anyway yes, it's not too hard to go from Lire to Euros and vice versa, still I am pretty sure a lot of ppl will get confused for a while...
Oh, and just as a side note, today I went to recharge my gf's cell phone at a bancomat stand, and the only currency used was Euro! :) I can say this is the first time I actually use it, so... Well... Nice!
