Very small relays, and high quality relays often have Gold plated Silver contacts, or just solid Gold bars as contacts.

The switches that are gols are gold overlay not solid. They are similar to rolled gold over silver. The best ones, if you have nothing to do, are on network switches. they need a high rate of reliability and the thicker gold gives that to them as gold does not oxidize.
