Interesting fact
The 5 Mark (Heinrich Hertz) coin from the German Democratic Republic (GDR) was minted in 1969 to commemorate the 100th anniversary of the birth of Heinrich Hertz, a German physicist and engineer who is credited with the discovery of radio waves. The coin features an image of Hertz on the obverse (front side) and a depiction of his famous experiment demonstrating the existence of radio waves on the reverse (back side). The coin was made of copper-nickel and weighs 12 grams. It was a non-circulating coin, meaning it was not intended for general circulation but rather as a collector's item.
