Lovely! I used to own a Francis I ecu d'or (raw Choice AU), but I swapped it for a fancy underwater metal detector years ago. Wish I still had it. Mine was ecu d'or au soleil, so a different type. I just got a biography of Francis I in audiobook format. Only just started listening to it. The Audible app will let me share a copy of that with you if you like. Just PM me if you want it.
