Odd medallion - any guesses on it?

[mazorj-migration]

Even though this is not a coin or even a medal in the usual sense of the term, I'm posting this here just to see if anyone might recognize it or venture an educated guess.

 

I inherited this oddity but know nothing about it. The only discernable device is the 5-point star. The reverse is blank, the edge is plain. It's copper, diameter is 24.5 mm, thickness 1 mm, weight 5 grams (all are approximate, +/-).

 

It may be nothing more than a cheap, rudimentary piece of jewelry, or it might have some recognizable significance. Any and all contributions are welcome.
