It looks like it's from the reign of Holy Roman Emperor Matthias (1612-1619) (I can see MATH RO I SEMP AVG obv)
Most coins from Spanish Netherlands (Belgium) during this period were in the name of Albert and Isabella (Archduke & Duchess of Austria), not Matthias. I am almost certain it is not a coin of Brabant or Flanders, which are what is often referred to as Belgium at this time.
But there were many small principalities nearby, each with their own coins.
The general design of the coin looks like the Brabant and Flanders 4 stuiver coin under Holy Roman Emperor Charles from the 1540s, but that is a much larger coin, not the coin that is shown.
@numis, do you have a KM number?
