A ballpoint that resembles a Copernicus model is most likely a counterfeit, since the Copernicus exists exclusively as a fountain pen, and only in the variants 4810 and 888. On counterfeit nibs, the inscription "4810" or with very bad fakes only "Iridium Point" is frequently found, while packagings of counterfeits often stem from other models like the Bohème. Original Copernicus pens cost new around 1,700 euros; counterfeit versions are sold for 20 to 50 euros online and for 2 to 4 euros in China. For reliable clarification, the comparison with original photos on the Montblanc website or at fountainpen.de as well as the visit to a Montblanc boutique is recommended.
