It's actually a Silver/Tin coating so 1) it resists oxidation, and 2) 
takes to soldering very well.  It's used extensively in the marine and 
military environments.  Uncoated (but plastic jacketed) copper wire 
corrodes rapidly in these environments.

I guess I don't understand the advantage here.  Silverware tarnishes about 
as quickly and easily as copper oxidizes, doesn't it?  Also, it seems to 
me 
one has to use special solder for silver.
