Something has to be.
Ag is relatively dense and monovalent. It also is available in high
purity and can be prepared qith few dislocations.

I can't say I am really satified with this answer. Wouldn't gold be
expected to be even more conductive then?
.. and does the temperature make any difference ? 
I don't get the joke. |

Not a joke, a question. Really cold copper, for example is a super
conductor IIRC. What happens to all those relativities of conduction at
temperatures other than 'normal/usual' ?

IIRC, the original post pleaded ignorance. I cannot produce a few words
that will magically make up for the ignorance.
The color of gold, and copper, is an indication that the plasma
frequency of the is relatively low. That in turn indicates that the
carrier (electron) density is low compared to silver. You do not
indicate that you understand the effect of purity and mechanical work
hardening of metal on conductivity.

Copper does not become superconductive. Lower temperatures do reduce
electron scattering off of phonons.
