1991 Hutt River Province Desert Storm Jeep

Hi everyone
My coin is identical in everything except it's not Brass looking, like the linc below, is this the same coin as the linc?
I know it's not the silver proof version
could it be a planchet error?

I suggest you to check the obverse (the front of a coin) to see what the coin is made out of. It might actually be a silver proof but just a bit dirty or circulated.

These medals are often made in gold, silver and bronze color

Hi thank you for replying, but this one is different than the ones listed in Numista
I took a picture of the edge also
