Description and research notes
Specimen of the issued 1970 one hundred francs type of the Grand Duchy of Luxembourg, bearing a red SPECIMEN overprint and circular punch hole cancellation across the central signature area. The note carries serial number A000000 in dual placement, consistent with specimen-format control numbering used for internal distribution and archival reference.
The punch hole cancellation serves as the primary method of invalidation, physically rendering the note non-circulating while preserving the full design. Unlike perforated specimen formats, this punched cancellation is typical of later production practices, particularly for specimens prepared for institutional reference or controlled release outside the printing workflow.
The design presents Grand Duke Jean in formal portrait at left, combined with layered guilloche structures and offset color fields engineered for clarity, durability, and machine readability. The integration of intaglio portrait engraving with multicolor offset underprint reflects the mature production standard of the 1970 issue.
As part of the Belgian Luxembourg Economic Union monetary system, this series represents Luxembourg’s maintained national identity within a shared currency framework. While circulating alongside Belgian issues, Luxembourg retained its own designs, engraving plates, and production specifications.
This specimen reflects the finalized and fully issued design, distinguishing it from earlier photographic proofs and gridline specimens used during development. It represents the completed production state of the note, incorporating all security, layout, and denomination elements as intended for circulation.
Surviving specimens of this type are more accessible than photographic proofs but remain limited in high-grade preservation. This example, with full overprint, intact punch cancellation, and original paper quality, serves as a reference specimen within the 1970 Luxembourg series and a key component in documenting the full production lifecycle of the issue.
