Depends on a few things.
-Who made it? - Pre 1968 Walther PPk's are worth more and are of the best finish and quality. They are the best for shooters and collectors alike
After the 1968 gun import law was put into effect the PPK was banned. This is when Walther entered into a contract licensing Interarms of Virginia to make the PPK over here in America to bypass that importation law. This is also when you get the PPK/S which is German made specifically to bypass the 1968 law. Both are in production simultaneously.
Then there is the S&W made ones which are finished equally to a lesser standard as the Interarms made ones, but they have a multitude of function issues. These will be worth less as well.
-Caliber- For German made ones 380 auto is the rarest, these are marked 9mm Kurz on the slide. For the rest it seems to be that 32acp is the caliber to find. 32acp or 7.65 Browning is the best working caliber anyways.
-Finish- All German ones are originally blued for the most part but a blued american made one is a rare sight since Interarms pushed Stainless pretty hard. For shooters the Stainless will sell quicker but collectors may prefer the blued version.
Need to know all that to ballpark it for you besides what condition it is in
NRA Excellent, Very Good, and so on.
Hope that helps some.
