I am quite sure that Friedrichstraße was the only East Berlin S-Bahn
station where one could buy S-Bahn tickets towards West Berlin in DM.
And only in the "non-socialist currency" area, i.e. the area which acted
as an exchange station for intra West Berlin traffic.

In the "eastern" part of the station there was a ticket counter where
you could buy the same tickets at the same price in East German marks.
And at least until 1984 those tickets were available all over East
Berlin. Maybe after 1984 only at Friedrichstraße, I'm not sure.

Were those at the subsidised price of 20 pfennig? It wouldn't surprise
if they would have wanted to see exit documents from the DDR if buying a
ticket into West Berlin, in which case presentation of a West German
passport would have immediately put the fare into Deutsch marks.
