/ AUTHENTICATION SERVICES

Verify Literary Integrity

Forensic spectrographic analysis and watermark verification to establish indisputable physical proof of historical manuscript and autograph authenticity.

FORENSIC METHODOLOGY

Three-stage verification

Our laboratory subjects every document to non-destructive physical testing, establishing a verifiable timeline through paper chemistry and ink analysis.

Spectrographic Ink Analysis

Substrate Characterization

Provenance Collation

We measure chemical compounds and pigment degradation under controlled spectrographic wavelengths to verify ink composition matches the documented period of origin.

Transmitted light analysis isolates internal watermarks, chain lines, and fiber density to confirm the geographical and historical origin of the paper substrate.

Our scholars cross-reference physical characteristics with historical archives and published collation formulas to trace and verify documented ownership history.

Core 4-Category Book Grading System

The foundational structure for a perfectly graded book or rare document.

SPINE

Evaluates structural condition and reading wear.

Pages & Interior

Evaluates internal page quality and preservation.

COVER

Evaluates the exterior visual presentation and structural integrity of the book cover.

DUST JACKET / SUPPLEMENTAL MATERIALS

One of the most critical aspects of the item.
