Apparently. Yes, this is bait-and-switch time! I didn't see the exhibit. Although I did actually poke my head in the door as the ticket-taker looked for some press info, I didn't have the time to tour the whole show.
But I don't mind. Even if you don't have time or inclination to see a Freak Show, it's worth the trip anyway. The grand and elegant interior of the Hôtel de la Monnaie is exquisite. To reach it, turn right just after entering the portals of the Monnaie building.
Climb the escalier d'honneur.
Admire the busts of Condorcet and friends in the hallway, and look out the windows at the Seine.
Imagine that you're attending a swish soirée in the salle de reception.
And while you're at it, look up at the fresco on the ceiling.
Then you arrive at the ticket desk outside the exhibit where you have to fork over your 6€ to get into the Freak Show. Up to that checkpoint the view is free. One of this month's better bargains in Paris.
The Monnaie de Paris is of course the Mint, where coins and medals are made. The grands salons are open to the public only when they are being rented for a special exhibit.
There is the Musée de la Monnaie, a favorite of mine and of all numismatists, at the end of the courtyard.
