Silver piedfort version

I have this coin but as a silver piedfort version ! I can’t find any information about it anywhere. Can anyone help ? 

I have no info about too, probably low mintage coin… if you have this coin, please duplicate the gold version page (there is option at the very bottom), change the composition from gold to silver, the weight, add “Piedfort” to the title and add your photos… if you have certificate, you can add photo to comments to! This is how Numista is working - users add the coins that they have in own collections.

As a Gibraltar referee, I will validate your request and Numista will be more complete.
