Germany, 5 euro collectors’ coin with a red polymer ring, "Tropical climate zone". The coin will be the first in a five-part series, "Climate zones of the Earth" (2017-2021, one to be issued per year), and is thus thematically linked to the first innovative 5 euro coin "Planet Earth" (a global premiere with its translucent, coloured polymer ring), which was issued in April 2016.
