DJR Expert Guide Series, Vol. 219 — Authentication of World Currency: Paper, Security Threads & Plate Numbers
World currency—modern and historical—is one of the most heavily forged categories in collecting. High-denomination notes, commemoratives, early issues, polymer notes, and rare replacement notes are common targets for counterfeiters. Professional authentication requires understanding paper composition, watermarks, printing methods, security threads, microprinting, serial systems, and plate-number structures unique to each country.
DJR Expert Guide Series, Vol. 219 — Authentication of World Currency: Paper, Security Threads & Plate Numbers teaches the complete professional framework used by numismatists, forensic document examiners, graders, and currency specialists. This guide breaks down how genuine notes are made, how modern fakes are produced, and how to detect subtle discrepancies using tactile, visual, and scientific methods.
Inside, you’ll learn how experts:
Evaluate currency substrates including cotton, linen blends, polymer sheets, and security fibers
Authenticate watermarks through translucency, shading, and molded-paper behavior
Distinguish genuine embedded, windowed, metallic, holographic, and microprinted security threads
Identify real intaglio printing using tactile relief and ink-flow patterns
Analyze microprinting, latent images, and nanoprint features under magnification
Verify serial numbers, prefix systems, alignment, color accuracy, and known block ranges
Interpret plate numbers, print positions, and batch markers used by national mints
Examine polymer notes for holograms, clear windows, laser-etched textures, and resist patterns
Use UV and IR light to reveal embedded fibers, fluorescence, ink differences, and hidden text
Detect washed, altered, patched, or chemically manipulated notes
Identify global counterfeit types including inkjet, laser, bleached-denomination, and offset fakes
Assess provenance, documentation, grading eligibility, and market value
Volume 219 provides collectors with a complete, professional-grade system for authenticating world currency—ensuring confidence, accuracy, and protection from modern counterfeits and altered notes.
