Hi Ron, welcome to the Luger Forum!! G-Date Lugers are found in one of six subvariations. There were about 55,000 G-Dates made in 1935. If you would tell me your serial number and the markings on the right side of the receiver, I would add it to my data base.
The value will depend on condition. The matching magazine will add to the value of your pistol. Photos would help!
