Does anybidy knows about France 5 francs 2000 commemorative coins are they magnetic or non magnetic?

Numista says non-magnetic
SCWC says magnetic
Same with:
All of these started out in Numista as either Nickel or Copper-Nickel plated Nickel but were then changed to just Copper-Nickel (or Aluminum Bronze for one of them).
Example N#17719
2012 - Nickel

2022 - Copper-Aluminum

Today - Aluminum bronze

And the best is the French version - Bronze-aluminium (Cuivre 750‰ et Nickel 250‰, plaqué nickel) which makes absolutely no sense at all.

Are you sure it wasn't Nickel plated Copper-Nickel instead of the other way around? I don't think I've ever heard about copper-nickel plating.
In Schön all these 5 francs are described as Nickel plated Copper-Nickel.

But I agree with you. It's a strange composition but there are others in the catalogue, right or wrong.
I've checked the Austrian coins in Schön and the 10 schilling and the bimetallic 50 schillings are indeed all Copper-Nickel plated Nickel there too.
You can't plate an alloy, at least not with techniques that are usually used in coin manufacturing.

That's why I suggested maybe they really mean “clad” not plated.
However, regarding the very first coin (Parisii stater):
After a quick search I found the louis d'or set on the internet. Since it is from the same series, it is likely the composition will be the same.

CoA here claims: Cu-Ni plaque Ni, so I suppose it is Cu-Ni clad Ni, because as mentioned earlier, an alloy cannot be plated

Translation for Cu-Ni plaqué Ni = Nickel-plated copper-nickel, just as Schön says.
And since Ma9nWaRr10 showed us a COA from the Monnaie de Paris, I think it's finally time to rectify the composition for once and for all.

I agree. Just make sure the French page is coordinated also or else we'll still have things like this
