The base of the coin is based on the shape of a Hussite chalice, but its lower part also has the shape of the observatory dome. The coin is issued to mark the 600th anniversary of the founding of the city of Tábor and the 80th anniversary of the founding of the Tábor Observatory.
This is a trackable item for the mega event GC8F8XP - Starry Tábor.
The last piece found at the bottom of the cabinet.
