They are indeed very recent. I just had someone grab me some of the lower denom jetons about 8 or 9 months back. But I think Carlos is correct, the French Roulette is no longer available at Aix-les-Bains. I was offered the same set of plaques and jetons recently, but had to pass on them, as I had already spent too much recently on some others from the same seller.
A very, very great looking set Carlos ! A unique and colorful design for sure.
