Interesting fact

One interesting fact about the Pattern 20 Heller coin from the Austrian Empire is that it was made of Gammametal, a unique alloy composed of 90% aluminum and 10% zinc. This coin was produced during a time when most coins were made of precious metals like gold, silver, or copper, making the use of Gammametal a notable exception. The use of this alloy was likely chosen for its durability and resistance to corrosion, as well as its ability to be produced at a lower cost than traditional precious metals.
