"100 Francs- Léopold I Duke of Brabant's Wedding" but it is not from gold

1. it is 3 gramms instead of 32 gramms. (feels like aluminium but still shines like gold)
   
2. there is no "L.WIENER"/ "LEOP.WIENER" writing under the heads.
   
3. and instead of "L.L. PH. M.V." , "Y.L. PH. M.V." is minted.
   

Цитата: "alpero"​I have almost the same coin as this but with 3 differencies:
​

1. it is 3 gramms instead of 32 gramms. (feels like aluminium but still shines like gold)
   ​
   
2. there is no "L.WIENER"/ "LEOP.WIENER" writing under the heads.
   ​
   
3. and instead of "L.L. PH. M.V." , "Y.L. PH. M.V." is minted.

​Is it fake? Does it worth anything?
