i remember that french currency deal in the mid ’60s i was riding my little peugeot 49cc motorbiike around paris, and when i needed to fill it up, i would tell the attendant “mille francs” (1000 old francs) and hand over a ten (new) franc note. either way, it was about two bucks worth of gas. the bike was a lot like a mo-ped, a lot of fun, but performance? not so much. it got me back and forth to classes.
i was back in the early ’90s and they had dropped the “NF” (new franc) notation from the bills.
