It's been discussed on here before. From a practical approach I think 
you will find the differences on HF to be slight.  Possibly on 10 a bit 
more, but with the large diameter tube and strap used ...The silver 
looks pretty. Of course if you're building something that'll make your 
own band openings...you might see a difference.  I've wound HF tank 
coils out of Copper for systems running well past 100 KW. Of course they 
had power to burn so-to-speak and they were water cooled.

You should see some of the big LF and HF induction heating generators.  
I don't remember any in the MF range.  IIRC there were also some RF 
powered plasma generators on an ISM band near 10 meters and they didn't 
use any silver plating either
