Collections of monetary artefacts bring history to life; their contents show how money has changed through the ages and act as reminders of the twist and turns of monetary and economic history. And their aesthetic quality means that the exhibits are often small works of art in themselves. A combination of pre-coin payment media such as stone money or lumps of electrum, 90,000 coins and 260,000 banknotes from every era makes the Deutsche Bundesbank’s collection one of its kind worldwide. The most important pieces in the collection can be seen in the Bank’s Money Museum. In the virtual internet museum, the collection’s experts regularly provide in-depth presentations of outstanding 'gems' from the collection.
