tarnished silver is the best, even better than gold.

The tarnish doesn't do anything good. On a relative scale,
silver is
250, copper 225, as is gold. Aluminum is 175. Stainless is
about like
lead, 6 or 8. Plain carbon steel is 25. Thermal conductivity is
closely correlated with electrical conductativity for what that
is
worth. Better at one is generally better at the other.

You boys worry about this WAY too much. Take a little reality
trip down to your favorite AM radio station and ask the engineer
if he'll show you the ground system at the base of one of the
towers. Don't touch the tower. It has kilowatts on it and the
arc will burn you. Notice how the bridge cables that have been
buried for 40 years look a little "tarnished" where you can see
'em. Half of 'em underground are just copper sulphate by now...

Your "tarnished" silver-plated ground strap is fine....mine, too.
