Could anyone pls tell me what this is, what it's made of and maybe even what it's worth. Thank you.

No one is starting what material it is. What is the best way for me to find out?

Precise measure of width, diameter and weight. Magnetic or not might be sufficient to roughtly determine the alloy.

I have no good way to measure the weight but it looks so impressive that it would be sad to make this out of anything else then silver. It is also non-magnetic and is colored a bit like something silver would I think.

"ping test" and “ice cube test” may confirm silver.

It weights 6.76gram according to my scale and is 2.5cm long excluding the top hanger. The surface area for a circle 2.5cm would be 4.1cm². maybe someone could tell me something with that info

The width is deemed necessary :)

But the width is very different. Couldn't we make an estimated width and then see if that is about accurate 

Aluminium: Thickness ~5,1mm

Coppernickel : Thick ~1,6 mm

Silver (pure): Thick ~1,3 mm

The ice-cube test is easy, compare with a 1 Gulden - Juliana (1954-1968)

Hoe exactly does the icecube test work and does it affect the state of my coin?

Ice cube test, there is absolutly no risq for your medal.

I've had a ‘senior’ moment here. The ice cube test is by far the simplest after the magnet. It capitalizes on the fact that silver is a great conductor of heat. There's a scientific name for this but can't think of it. Of course, copper is as well, which is why better stainless steel cookware have copper bottoms. But silver is better.

There's also a fairly simple density test, outlined in the hard-to-find https://en.numista.com/numisdoc/. 

The density test by immersion in water is much more complex to perform. For good accuracy, it is best to use a container with a narrow neck.
