Believe it or not, this is actually used by many phototypsetting firms
to recover the silver in the fixing solution.  Apparantly, they can recover
enough of the silver to make it worthwhile salvaging.

You have also demonstrated a simple electroplating principle with your
experiment.

Yeah, those days were fun....
