 a friend of mine has just inherited a few old German bank notes form the 1920's-1930's
 I believe these are only worth a few dollars a piece, am I correct?

Wow, that was difficult.  If you had posted a picture of the other side with the Pick number it would have been easier.

The holder says UNC $25.

First I though the note was a P182a in UNC worth $35-$40.

P182 50 Reichsmark 30.3.1933. Green and black on multicolor underprint. Portrait
David Hansemann at right. 7 or 8 digit serial #.

a. Watermark: David Hansemann at left. With underprint letter.
b. Watermark: Ornament at left. Without underprint letter
(1945).

But it is actually a P196a 50 Mark and worth at least $80

a. 9 digit serial # with F. 20.00 40.00 80.00
b. 9 digit serial # without F. 10.00 30.00 50.00
c. 8 digit serial # with dash, with F. 60.00 150. 600.
d. 8 digit serial # w dash, without F. 20.00 40.00 80.00

Correction b. 9 digit serial # without F. $50.00

Thanks I was only sent that photo I have never seen the notes in person
