they look like they contain more than the usual amount of silver that you find in electrical stuff.
i dont have anyone to sell this sort of stuff to - so i just end up dumping it with my copper or brass.
i suspect i must have thrown away altogether a few pounds of silver in all the years ive been scrapping.

Nice contacts, they might contain a small of amount of cadmium, which is also present in many silver solders if your going to heat the buttons to remove them just do it outdoors. Depending on what these were used for they may also contain platinum / iridium or even palladium alloyed with the silver.
The pair on the left hand side look like there may even be a slight bit of gold in the solder used to braze the buttons in place.
