Bundesbank Bunker Cochem.

The West German government became increasingly concerned that hostile communist states may flood the country with counterfeit banknotes. This would devalue the Deutschmark and destabilize the country’s economy as a precursor to an invasion from the East.

So Bundesbank launched a cunning plan. They printed an entirely new secret currency and put them in storage. If Russia and its allies launched an economic attack, the old bills could be withdrawn and new banknotes issued within a matter of days. This would cancel out counterfeit currency.
