12 Kreuzer - Leopold I indented shield

Hagenau's 12 Kreuzer issues of this period reflect the city's precarious autonomy within the Holy Roman Empire following the Peace of Westphalia. France had formally received supervisory rights over the Alsatian imperial cities in 1648, a deliberately ambiguous clause that Louis XIV would spend the following decades exploiting — Hagenau itself was effectively absorbed into French control by 1679, which terminated the city's independent minting activity altogether.

The indented or incuse shield variety distinguished by E&L#90 represents a specific die treatment separating it from otherwise similar Hagenau issues of Leopold I's reign.
