20 Lei - Carol I Reign of Carol I, brass pattern

This is a pattern strike from Romania's 1906 Jubilee year, commemorating forty years of Carol I's reign — a period that had taken the country from an Ottoman vassal principality to a fully independent kingdom. Pattern coinage from this issue was produced in multiple metals and alloys as the Romanian monetary authorities evaluated designs, and the brass strikes occupy a middle tier between the base-metal trial pieces and the precious-metal presentation examples. Stamb#1.3 distinguishes this specific alloy variant within what is a small but carefully documented family of pattern types.
