Gold is best, and preferred to silver or tin because a layer of it can be so much thinner.

Is it high frequency? Skin effect will put the current in a thin layer and silver may be worthwhile. If bulk resistance then use copper it is the second most conductive metal. Aluminum is used because it is cheaper but it has connectivity problems.
One nice thing about silver is the corrosion products conduct so even when it is black it is still useful.
Gold is used because it is chemically inert. It isnt great as a conductor of electricity though. Tin is also used for oxidation reasons. That is why in years past cans were tin plated - thus the term tin can.
It isnt great as a conductor though compared to silver.

Electrical Conductor, any material that offers little resistance to the flow of an electric current. The difference between a conductor and an insulator, which is a poor conductor of electricity or heat, is one of degree rather than kind, because all substances conduct electricity to some extent. A good conductor of electricity, such as silver or copper, may have a conductivity a billion or more times as great as the conductivity of a good insulator, such as glass or mica. A phenomenon known as superconductivity is observed when certain substances are cooled to a point near absolute zero, at which point their conductivity becomes almost infinite. In solid conductors the electric current is carried by the movement of electrons; in solutions and gases, the electric current is carried by ions.
Most metals are good conductors.

Silver is the most conductive metal, followed by copper.
Copper is very cheap and very well suited for nearly all electroics applilcations.

Copper and aluminium are the best alternative in terms of cost and properties.

If it is the expenses that you are worried about use copper.

go for copper
