A counterfeit can be recognised by several details: the imprint on the nib is far too flatly stamped and only partially platinum-plated, the serial number is, on the original, laser-etched and executed in an unmistakably different font, and the converter differs clearly on originals from the converters used in counterfeits. These points alone allow an unambiguous identification in many cases. Filing a complaint with the prosecuting authority experience shows little — more sensible is the reversal of the purchase.
