It complements the issued note and other developmental material by revealing how the adopted composition was derived through controlled adjustment rather than abrupt redesign. Read more →

Luxembourg 29 July 1965 - 20 Francs Face Photographic Proof Early Design Concept (Pick Unlisted)

The signature area is already present, indicating that administrative elements were being considered in parallel with design development. However, their placement and integration do not yet reflect the refined balance seen in later stages, reinforcing that this proof belongs to a conceptual rather than finalized layout phase.

Luxembourg 29 July 1965 - 20 Francs Back Photographic Proof Early Design Concept (Pick Unlisted)

Unlike the finalized reverse design-featuring the more complex valley, dam, and engineered river control structures associated with the issued Pick 54-this early concept emphasizes a pastoral scene with minimal architectural intervention. The absence of tightly integrated guilloche framing and reduced ornamental precision indicate that the reverse design had not yet reached its final technical configuration. Read more →

Luxembourg August 1965 - 20 Francs Back Photographic Proof Transitional Design Stage (Pick Unlisted)

Luxembourg 1951 Banque Internationale a Luxembourg 100 Francs Multi-Stage Photographic Proof Assembly (Pick Unlisted)

Handwritten archival annotations are present on both sides of the assembly, with “28 July 1951” appearing on the front and “15 June 1951” on the reverse, documenting separate stages of internal review during the active design phase. These dated references firmly place the assembly within the development period, approximately five years prior to the finalized issue. Read more →

Luxembourg 1956 Banque Internationale à Luxembourg 100 Francs Face Photographic Proof (Pick Unlisted)

No serial numbers appear on the face, consistent with the issued format of this note, where numbering is carried exclusively on the reverse. This reflects a finalized structural decision within the series, differing from the earlier 1951 design stage in which serial numbering was still placed on the obverse. Read more →

Luxembourg 1956 Banque Internationale a Luxembourg 100 Francs Back Photographic Proof (Pick Unlisted)

As a photographic proof, this piece served internal review and verification functions within the printing process and was never intended for circulation. Surviving examples are scarce and provide direct documentation of how the reverse moved from design concept into production-ready execution. Read more →

Paraguay 1907 - Banco de la República 5 Pesos with 1912 Dual-Side State and Treasury Revalidation Overprint (Pick Unlisted, Base Pick 156)

Uncirculated 1907 Banco de la República 5 Pesos note, printed by Waterlow & Sons, London, and later transformed by the 1912 Paraguayan emergency revalidation process. The note is based on the original 1907 Banco de la República 5 Pesos issue, cataloged as Pick 156, but this dual-side state and Treasury validation format appears to stand outside the standard catalog listing and is therefore best treated as Pick Unlisted, base Pick 156. The face carries the large oval state overprint “Emisión del Estado – Ley de 11 de Enero de 1912,” while the reverse bears the additional Treasury validation “Departamento de Hacienda – Junta Fiscalizadora – Cincuenta Centavos Oro Sellado – Conforme Decreto de 20 de Mayo 1912.” This dual-side structure places the note among the most historically informative forms of Paraguay’s 1912 provisional paper money.
