20 Haléřů Trial Strike

Trial strikes from the Czechoslovak State Mint in the early 1930s were produced as internal production tests rather than for submission to any approving authority — the designs for circulating coinage had largely been settled in the previous decade. This piece exists in the gap between confirmed approval and full production runs, struck to verify die alignment, alloy behavior, and press calibration. Very few left the mint in any official capacity.

KM# Pn10 is one of several pattern and trial designations from this period that remain incompletely documented in the primary literature.
