Verification for Treasury Secretary Samuel D. Ingham | Item # 1344
Autograph Authentication – Samuel D. Ingham
Confidence Grade: A (Most Likely Authentic)
Overview
The document under review is dated “Nov. 25th, 1830” and appears to be issued by the Treasury Department of the United States. It contains a printed form letter that has been filled in by hand and includes the handwritten signature of Samuel D. Ingham, who served as Secretary of the Treasury under President Andrew Jackson (1829–1833).
- The signature and other handwritten parts exhibit strong signs of contemporaneous inking and physical contact with original materials. The flow and ink displacement suggest a dip pen and iron gall ink consistent with early 19th-century practices.
- Candidate Identity (Confirmed): Signature matches strong-exemplar examples of Samuel D. Ingham’s known autograph style from official government correspondence during his tenure.
- Key feature alignment: angular capital “I” in “Ingham”; looped descenders in “h” and “g”; slight southeastern tilt; flow tapering on his “S. D.” initials.
- The document includes no visual markers present in known mechanical reproductions (such as autopen, printing inconsistencies, or telltale laser-printed artifacts).
Given the congruence of this handwriting style with authentic period documents, strong forensic consistency with early 19th-century dip pen characteristics, and absence of reproduction errors, this signature is assessed as most likely authentic.
Forensic Ink and Substrate Evaluation
- Ink Type: The handwriting shows traditional iron gall ink traits typical of the 1830s — dark brown-black tone with light feathering and absorbency. The ink has slightly oxidized in areas, showing natural chemical aging.
- Ink Saturation and Bleed: There is visible ink bleeding into the substrate fibers under close inspection, especially under scripted flourishes — a key indicator of genuine pen-to-paper contact.
- No signs of ink pooling, toner spots, or pixelation that often accompany printed or photocopied reproductions.
- Pressure Variations: The signature demonstrates natural fluid dynamics — varied line pressure, organic starts and stops, and tapering at entry/exit points of strokes. These features are incompatible with autopen or printing.
- Substrate Material: The substrate is consistent with early 19th-century rag paper. Visible watermarks, light creasing, and minor foxing support the period authenticity.
Individual Signature Analysis
Signature: “S. D. Ingham”
- Letter Shape and Formation: The capital “S” and “I” match samples from verified Ingham signatures found in National Archives collections and official Treasury Department letters from the same period. The “D” in the middle initial is cleanly formed with characteristic loop-over-shoulder formation.
- Stroke Characteristics: Features include:
- Slight hesitation before the initial “S,” then a confident flourish.
- Flow interruption and pen lifts at expected points consistent with dip pen ink recharging.
- Handles pressure with an organic stroke width — completely incompatible with mechanical/print processes.
- Forensic Signs: Ink pressure trails and flow transitions are authentic.
- Tapered stroke endings indicate handwriting, not a reproduction.
- Crossbar of the “h” slightly fades toward exit, reinforcing authenticity.
Addressee Signature: “Samuel Swartwout”
- Historical Note: Samuel Swartwout was Collector of the Port of New York from 1829–1838.
- Style Analysis: Legibility is low but characteristic of his known signatures. It exhibits:
- Casual cursive with strong end flourishes.
- Feathered pressure drops and slight slant instability indicating genuine flow variation.
- Signs of Authenticity:
- Natural irregularity in character sizes.
- Light ink diffusion at stroke terminators.
- Visible pen lift evident in formation of terminal “t.”
Collective Signature Analysis
- Consistency: Both primary and secondary signatures were written in the same inking method and period-appropriate style.
- Rhythm & Temporal Credibility: Ink consistency between names and body text suggests contemporaneous execution. No discrepancies that would imply replacement or pasted graphics.
- No Repetition Patterns: Careful inspection reveals original, freehand execution with natural strokes. No matching pixel clusters or evidence of digital or autopen reproduction.
Red Flags
- None Detected: No signs of autopen (e.g., uniform line weights, “machined” wiggles), printed replication (no pixel overlap, print raster), or photocopy artifacts.

Final Comments: The evidence reviewed shows high concordance between the ink artifacts, paper substrate aging, signature stroke quality, and authentic exemplars. This item represents a highly probable authentically signed letter from Secretary Samuel D. Ingham to Samuel Swartwout, Collector of the Port of New York. All indicators support that the document and its signatures date to the early 1830s and were executed with period-correct materials.
