They most probably contain some silver along the copper i see inside the wire, if you can really pile a whole lot of them maybe it's worth testing or doing a research.

From the peanut gallery- they look like caramel candies. Probably don't taste like them though.

Are these capacitors? Old capacitors can have palladium alloyed with silver and other precious metals depending on type.

These are polyswitch resettable fuses, also known as positive-temperature coefficient fuses.

Generally, I've seen several types of components made of a wad of homogenously mixed particles compressed into a pellet, through which electricity is meant to pass. To connect wires to the pellet, they put a thin metallization of metal on either side of the pellet. This metallization is sometimes silver. (it often looks like silver, I only tested rarely)
