It's a 1902 Dutch medal made for a certain Eucen Cucel, a teacher a the Polytechnic school in Delft, South Holland.
It was made by his students to celebrate his 70th birthday and given to him on the 26th of March 1902.
Thanks for the info Apollo. No one ever gave me a medal for my 70th. That teacher must have been very popular. I can't recall from where I obtained the medal, probably from an auction lot that contained 1 or 2 items I wanted, and this came along with the lot. I know I would not have been interest in this alone.
