Sad news (or quel fromage, as we say at the Global Worldwide Headquarters):
The storied currency of France is now officially defranct.
From Sunday’s New York Times:
As Old Francs Expire, France Makes a Small Mint
PARIS — Greece may be scrambling for revenue, but the French treasury has just banked some 550 million euros for doing nothing — simply letting the French franc, created in 1360, finally perish.
Friday was the last day that French francs could be turned into the Bank of France, the central bank, in exchange for the common European currency, the euro, a little more than a decade after it was introduced as bills and coins. The approximately 550 million euros represents the francs still outstanding, somewhere, which are now worthless, and which will be registered as revenue for the French state.
Campaign Outsider Flashback (pat. pending):
The hardworking staff (and the Missus) went to Paris in 2002 just as the euro was launched. You could buy one euro for 81¢ American at that point.
You bet we could afford the appetizers on that trip.

The missing francs are probably under Brigitte Bardot’s bed.
No – that would be the missing Franks.
If that comment refers to her most recent husbands, you, sir, are a genius.
I’ll accept that, Mick.
Dang! Those 10 centimes coins used to make great MBTA tokens.
Plus ça (pocket) change, eh, Mike?
The hardworking staff is on a (baguette) roll.
Anyway, no worries, Michael; if it took France this long to get rid of their currency, imagine how long it will take the MBTA.
