Try using a polarized light source and filter.  The reflective silver areas
should darken much more than the normal parts of the photograph.

If this doesn't quite do the job, perhaps you can subtract two photographs
made with different polarizer orientations, create a mask of the areas that
changed value most strongly, then use that mask to selectively darken the
silvered areas.
