The Luger you show..depending on an in hand inspection could be worth $18-2500. Holster is $3-375 depending on what the back of it looks like. Might be a lot less if there is a nasty surprise back there.
Does the tool have any markings?
Looks like you have 2 magazines? extra Magazines other than one with the pistol can fetch $100-150 depending on markings and condition.

Oddly enough it's often best to sell the holster, tool and extra magazine seperately. Most people who want to buy the pistol will want those things thrown into the deal...
