Fines is known (both silver parts are 0.950) and already entered in Numista database, if I correctly understood. The problem is why this is not displayed on Numista coin page.
Anyway, this coin is triple-elements bimmetallic and not trimettalic ;-)
Yes, you are right, I myself have just approved a modification request from a user who has given me the fineness data based on a test XRF (Xray Fluorescence Spectroscopy) that he has made on his own coin, giving the result of silver 95% and copper 5%. I hope I did well in passing it, are these tests really reliable? From what I've researched, I think so.
Actually, the problem that I indicated here is that the fineness was not indicated in the Features box (as MMowiec comments), and which, as rsirian1 has very well said, I think I should have been write in the Numista Website Forum as a “bug”.
Regarding the trimetallic issue, they are really two metals distributed in three parts, since the interior and exterior are made of the same material, but I believe that these coins have always been considered that way, like this one, perhaps the best known, from France.

If not, how should it be indicated? What is your opinion?
