USING OLD FRENCH STAMPS TO MAIL LETTERS

During my many visits to France over the years, I managed to pick up a few extra stamps denominated in French Francs. With the changeover to the Euro, I wasn't sure whether or not these stamps could be used, but I've used them without problem several times over the past few months.

I paste them onto the envelope and then the post office clerk calculates their value in Euros. After that, I simply pay in Euros the remainder of the amount due, usually several tens of centimes.

It's a good thing, because I have quite a few stamps which I would be more than happy to be rid of.
