Common Currency

Since it's a new year anyway, we may as well introduce yet another currency. January 1st, 2002 saw the birth of the euro; in the meantime, that currency has become (surprisingly to some) virtually equal in value to the United States dollar. So why not join the two together? Ladies and gentlemen, allow me to introduce the eurollar.
But seriously, I think the fact that the currencies are now basically worth the same makes transatlantic communication much easier. You can just say 'this stupid thing cost me seventy bucks' and both continents understand how much you were ripped off for.
