The Brno interregnum deniers of 1097–1099 fall within one of the most turbulent succession periods in Moravian history, following the death of Bretislaus II and the disputed claims that fractured the Přemyslid holdings across Bohemia and Moravia. Cach 405 is among the scarcer attributions in this series precisely because the issuing authority itself was transient — coins struck without a reigning duke tend to survive in smaller numbers, as production was neither systematic nor prolonged.
