Charles Philip of the Palatinate died in 1742, making a coin attributed to him dated 1758 an immediate flag for misattribution or a posthumous issue struck under a successor continuing an older type. The Palatinate's billon small change of this period was produced in enormous, poorly-documented quantities, and die re-use across nominal reign attributions was common enough that catalog assignments like KM#377 sometimes reflect convention more than strict historical accuracy.
