Any idea what it is made of? [επιλυμένο]

I worked on this project, and was given this medal.  Has anybody figured out what it made of?

See https://en.numista.com/numisdoc/determining-the-metal-of-a-coin-27.html

Sizes - diameter, thickness?  Weight?  These could tell you much of what you need to know.  

It is 106 g, 5 mm thick, 60 mm diameter.

So, volume = T  * π r^2 = 14,137 mm^3 = 14.137 cm^3

106/14 = 7.57 g/cm^3 

Mostly Iron would be my guess.
