GERMANY. Palatinate (Pfalz). Ducat, 1662. Heidelberg Mint. Karl Ludwig. PCGS Genuine--Cleaned, AU Details Gold Shield. Fr-2001; KM-94; Memmesheimer-2331. Weight: 3.46 gms. A SCARCE type overall, this example still retains a great deal of brilliance and only very light handling. The noted cleaning is barely evident, and it remains quite pleasing as a representative issue of the reign. Ex: Stacks (1/2008) Lot # 2715.
