What is the value of Mauser-Werke AG Oberndorf AN Cal. 7.65 drpuap?

You have a Mauser .32 Auto. It was made in Obendorf- D.R.P.u.A.P. means "Deutsche Reichs patenten und Auslandische Patenten" (German Patents and Foreign Patents). Usually found on commercial, non-military guns.

Value could be anywhere from $50-$500, depending on exact model, condition, and originality. This will really need a hands on appraisal by someone that knows European guns. We simply can't do it sight unseen- sorry.
