15 years ago my Uncle gave me this print and told me it was worth a lot of money. When you hold it up to the light you can see the Rembrant water mark.

What exactly are you asking, please?

I want to know what it is worth?

Here is further information about the original work: Anatomy Lesson of Dr. Nicolaes Tulp - Wikipedia, the free encyclopedia

Now as this is a print, it is unlikely that it will be worth a great deal, unless it is a signed limited edtion of SMALL numbers.
