Austria 1957 5 groschen
The specimen shown is an example of a type struck in Austria, 1948-94. This date is common but the proofs are rare. Zinc oxidizes quickly in moist air; uncorroded specimens are few. Austria began minting euros in 2002, rendering this coin obsolete. The old Hapsburg eagle clasped an orb and scepter, symbols of imperial power; the republican eagle holds a hammer and sickle, symbols of the hard work needed to rebuild from the disaster of World War Two.
Recorded mintage: 26,809,000 plus a few proofs.
Specification: 2.5 g, zinc, 19 mm diameter.
Catalog reference: KM-2875.
