How much is one of these cartridges wort ?

Not Much! This is a fairly common 9mm Mauser cartridge and even in good condition is only worth $1-$2 per round.

It is a nice headstamp with the Nazi eagle and is from a historically interesting time, but it is not unusual.

This kind of cartridge is what makes cartridge collecting fun. Interesting items that are deeply associated with interesting historical periods are relatively cheap to accumulate.
