any idea what kind of metal this is

Hi everyone I don't know if I should post this question here or somewhere else I'm not familiar with forums and how they operate but im trying to learn, my question is what type of metal or metals these contacts are I have a lot of them but would like to know what they are made of before I start putting time into getting them off thanks everyone Moses

It can be many things, testing it may be necessary to find out.

That looks like a switchcraft switch and if so it will probably be silver contacts

That's obviously a large piece of rusty steel. No values there.

I see what looks like a cardboard box and a rusty pair of wire cutters also.

I see silver contact and coated plate of brass/bronze. Eventho im not quite sure it is electrical, as for the silver contact.
But the edges clearly show some brass where it was scratched by dragging it on the ground.

you have nitric acid?
in any case, any scrap miner should have it !!!!
you take it, bite off the contact, throw it in acid. If the contact is made of platinum or gold, it remains intact and will shine brightly. (check the white one with a magnet - it may be a tungsten alloy),
if there is palladium in the alloy it will give a coffee color around the contact.
If this silver dissolves, then you add a pinch of salt and chloride will form.

I have a question.does anyone know what this metal is?

I don't want to add this to aqua regia in gold foils so I have picked them out.

Little back ground where it came from. Patches of Gold filled jewelry after nitric foils and these remained. It's not magnetic. I don't want to do aqua regia on it if it's palladium or something cause I don't have the required chems to percipitate back out. It's 14.77 grams and i prolly expect more from my last patch in nitric in progress.

Any clue so I know what to do with it would be great. Thanks

Also if u have a clue how would I test it in metal form not solution to find out if your thoughts are correct?

Nitric will dissolve Pd.
My guess is that it might be one of the Stainless steel classes of material as they do not dissolve or are hard to dissolve in Nitric.
They are not magnetic either.
They do dissolve in HCl though.
