Hi BjC,
this coin is a Dubbeltje of Willem the third.
they make in 1890, 2.600.000 of them in silver.
The name dubbeltje for the coin became so , there where in that time 5 cent pieces and when you had two of them then it was the same worth of a dubbeltje.
Dubbeltje means (doubel ?) two times the valeu of 5.
the worth of the coin is about 4 dollar.
