Certification Number: [Inserta aquí el número de certificación] MINT ERROR DETAILS: This coin is officially certified on the holder as a "MINT ERROR - Struck Thru Obverse". This mechanical error occurred at the mint in 1909, when a foreign object (such as grease, a metal scrap, or cloth debris) got caught between the die and the silver planchet during striking. This left a distinct, indented impression on the obverse over the historic portraits of Frederick the Quarrelsome and Frederick Augustus III. Since the error is fully authenticated and guaranteed by [NGC / PCGS], it eliminates any doubt about post-mint damage. A rare opportunity to acquire a high-grade historical silver crown with a dramatic and certified mint error!
