War Wheel is correct, it would also help if you’d personally know some war historian/antique collector whom you trust. People interested in historical stuff tend to know each other and know who wants to buy what and what it’s worth…
My experience is more with guns than knives but I’ve found the following to usually be true. Most WWII weapons were mass produced on a scale never seen before or since and are generally not as valuable as people think. I’d have folks come in with Japanese rifles acting like they had a piece of Christ’s cross. They were usually worth 60 or 70 bucks. The point being, if Uncle Joe brought back such and such relic from the war, the trophy is usually more valuable as a touchstone and a family heirloom than whatever it would bring in when sold. There may be an auction house or antiques dealer in your town. Swing by there and let him take a peek at it so you can get a general idea of it’s worth.
Please post the pictures. If you have any background on the knife, i.e., was it issued to a family member, captured, etc, pictures/documentation may add a bit to the value, post some of that too.
Also, if any dealer/collecter says anything to the effect of “I don’t collect that type of thing but I could give you a few dollars for it.” Immediately leave the premises with the dagger.
There are basically two types of SS daggers, the early maker marked and the RZM type.
A trully near mint early SS EM will sell for about $ 5000 USD and $ 3500 USD for the RZM type.

It looks more like this; but is not a copy or replica
The above cannot be overstated. There are so many replicas/counterfeits that provenance or background can support that it is original and also add to the selling price. Taking the extra time will be worth it.
