Help with coin identification

any idea wha coin this is?

If you squint really hard you might see a lion with a paw on a double tablet. Which is a common image on a lot of 19th to early 20th century belgian copper coins: https://en.numista.com/catalogue/index.php?e=belgique&r=lion&st=1-2&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=1832-1919&i=&b=&m=3&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

I agree with SGreg85. What are the dimensions and weight? That will narrow it down.

20 mm en 2 gram 

Then  I am guessing it is a 2 cent coin. It should weigh 4g, but a lot of the coin seems missing. Size should be 21,5 mm, but same probable cause.

Those were made from 1833 to 1919, covering 3 kings. To narrow it down again you need the obverse, with date and royal monogram.
