Any Idea of Collectability?

My father has just "dug-out" of his achives, a silver(Chrome I think) Luger that has a crown above Ereurt and 1916 stamped on the chamber. All the numbers match. The grips are wood, but are not checkered, they are smooth. Very little pitting. I was/am very intrigued, as he said he has had it for 50+ years. Is it worth anything or does it simply have sentimental value. As you can see, I am clueless. Thanks in advance for the help.
