17 September 2018, Hessen, Frankfurt/Main: Small euro signs can be seen in the figures of the revised 100 and 200 euro banknotes during the presentation at the headquarters of the European Central Bank (ECB).  They complete the second generation of euro banknotes. The new notes are to be issued from 28 May 2019. They should also be harder to counterfeit than before. Photo: Arne Dedert/dpa
