Cius, the Propontic city that struck this issue, was one of several autonomous mints producing posthumous Lysimachean tetradrachms under royal authority during the king's final years. Lysimachus was killed at the Battle of Corupedium in 281 BC — the last of the Diadochi to fall — leaving his kingdom to collapse almost immediately. That abrupt end compressed the active minting window for this type to roughly seven years, making city-attributed examples traceable and historically anchored in a way that the later posthumous series is not.
