1 Heller

Teschen's heller issues of this period fall within the duchy's administration under the Habsburg crown following the Thirty Years' War, which had ended with the Peace of Westphalia in 1648 — leaving Silesian territories like Teschen economically exhausted and their small-denomination coinage in chronic short supply. The heller, among the lowest practical denominations struck in silver rather than billon or copper, reflects the particular monetary conditions of post-war Silesia, where debased wartime currency had so thoroughly eroded public trust that even tiny silver fractions commanded acceptance over base-metal alternatives.
