Luger value

I have a Luger that was my father in law's. I was wondering what it might be worth. It has a date of 1920 and all the numbers match. it has some initials on the top DWC or DWM I cannot decipher them. The gun is in pretty good condition,the wood is a little worn but most of the bluing is fine. Could you give me a price and maybe tell me a little about the gun? If you could halp in any way I would be very appreciated. Thank you,
