Nice coins! That French coin is one that I want to get myself (though I am looking for the crown size 5 francs). It has a striking similarity in style to
this coin from Venezuela. That is because they were both done by the same designer/engraver, Barre. His name is below the bust.
The France 2 francs is KM#807.? depending on the mintmark. 900 silver and 10g. Book value at about $10 +/- in Fine. A few million minted at each mint.
The sol is a favorite of mine too. I picked one up too not too recently. They are beautiful coins. Yours appears to be KM#196.26 (there are lots of varieties with this coin.) Also 900 silver at 25g. Book value at $6/7 from Fine/VF which I think your coin stradles.
