Montblanc Serial Numbers: What They Say and What They Don't

Serial numbers appear in different positions and formats depending on the line and period. Their presence can help document an item, but they do not function as a standalone certificate.

Fakes also reproduce sequences and engravings. A plausible number on an inconsistent pen still requires further investigation.

Photograph the engraving for your inventory and insurance documents. In public listings, it may be prudent to obscure part of the sequence to make unauthorized copying more difficult.

Compare typography, position, and finish with documented units of the same reference. Seek specialized assistance when the value justifies it.
