1888 Franz ferdinand 20 mark fake?

This is my first post on the forums so hello, nice to be here. Anyway, I inherited few albums from my grandpa and now I'm determing it's value. And this coin kinda bugs me, as the topic says its 1888 Franz Ferdinand 20 mark coin but it isn't gold, which you can see just by looking at it, and also weight doesent match (it's only two grams instead of 8). Problem is all I found on Google were gold coins from that age and denomination. So I'm wondering is it fake or special (would prefers special   ). Anyway any help appreciated, thanks in advance.

Looks indeed fake
chrome or silver plated

Okay, sad news but thank you for contribution.
