Poland 1951 – Nicolaus Copernicus 

Nicolaus Copernicus appears for the seventh time in our list on the highest-but-one value in a set of six issued to mark the first Polish Scientific Congress. The other subjects in the set, in ascending order of value, were: Stanislaw Staszic, a leader of the Polish enlightenment; Marie Curie; Zygmunt Wróblewski and Karol Olszewski, a pair of chemists and physicists who worked together; Marceli Nencki, a biochemist; and finally a coat of arms with the inscription ‘1st Kongres Nauki Polskiej’ and a symbolic dove and book.
