I wonder if an electroplater could help you? In theory any electroplater could do this, they may have to buy an electrode and silver solution if they don't already have them. But they probably do as getting things gold & silver plated is relatively common. I've 'googled' few links about this.
This firm is a Qld based electroplater:

This firm actually says they do silver plating:

And this firm supplies both the silver solution and electrodes:

This is wikipedia's page on electroplating:

Hope my 2 cents comes in handy.

I had someone else ask me a similar question some time back.
As it turns out I found his car was fitted with a hidden gps tracker, his phone was tapped, his locked garage, and house were all comprimised, laptop spyware, mobile phone left trail.....etc etc
He asked me to remove it! And I said have you got anything to hide and he said No.
My advice was to leave everything in place and carry on as normal.
He often gets baited but he is ok with that now he is enlightened.
If it is Legit / not stolen and you just want privacy
Walk to a bus stop, leave mobile phone at home, go out of town then visit a small frieght forwarder......not the post office they are nosey buggers
If you have someone you can trust with your life send it to them 36 months before asking about avoidence / deception on a public
There are better ways to avoid a paper trail but I only consult in person on such matters depending on the requirements (-;

Holey toledos 10 large face value, that'll be worth dome dough in Au coins thats for sure.libertadiac said:The spray isn't paint - quoting from box it creates a molecular bond identical to electroplating - with any plating method it will be difficult to remove. Back to the OP, as per another thread, the face value of coins means you can take $10000 face value without declaring so you don't need to disguise them.
