If you're very adventurous you could try stripping the coating and silvering it yourself. I haven't done it so I can't comment on its effectiveness but my understanding is that it takes multiple attempts to get good at and it involves lots of nasty chemicals. The reading I've done seems to indicate that if you make a mistake you can get silver nitride which has a tendancy to explode

If you're thinking of silvering, read up on it yourself to weigh up the risks.
