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.
