Genuine French 5 Francs?

For the most part it appears authentic. There are three things that cautions me from saying that it is real.

1). The extra metal on the edge.
2). The denticles are not even all the way around the edge.
3). The condition of the coin for it's age.

It makes two of us - I completely agree with derf and would be very cautious about this coin.

try some of the many silver tests (ping, ring, ice, neodymium....)
a coin in that quality is difficlut to find

Beware: if a coin is valuable, the chinese are making copies
here is the catalog value (= not the real buying/selling price)

May be worth asking French forum
"Authentique ou copie ?"
And if it is an auction, and you have no weight, says it, they'll ask !
"je ne connais pas le poids".
Good luck !

Look at the bottom left of the obverse. The inconsistent denticles, where it gets thin, is an instant indicator for a fake

may we see the edge?
does it say, in relief on the surface, <<DIEU PROTÊGE LA FRANCE>> ?

Thank you all for your responses, I shall update with relevant pictures and measurements when I receive the coin.

Okay so it weighs in at 25.03g, which seems accurate and its diameter is approximately 37.2mm so a tad over but not necessarily any indicator of authenticity? The edge is indeed in relief with the words *** Dieu protege le france. In all, these signs are good. What does everyone think?

​If you look at the Numista page for the coin the denticles are uneven in the exact same place!

There are a few specialized collectors of 5 francs out there ...
