The emergency notes were originally stored in this underground bunker in Germany, which now serves as a museum. The faces of these bank notes were almost identical to the real ones then in circulation, but the backs differed substantially. By the 1980s, as the Cold War neared its end and bank note technology became more sophisticated, the secret currency no longer met Bundesbank security standards. After the Cold War, the bunker became the property of a regional cooperative bank and then a real estate fund. It was bought in 2016 by German couple Manfred and Petra Reuter, who turned it into the Bundesbank Bunker Museum that is still open to visitors.
