How to Spot Fakes at Home
While formal authentication requires microscopic and algorithmic analysis, there are major red flags you can spot with a simple jeweler's loupe.
1. The "Hesitation" Check
When a person signs their own name, it relies on muscle memory. The pen moves rapidly and smoothly. When a forger copies a signature, they are *drawing* it. This fundamental difference leaves physical evidence.
Look closely at the curves and loops. A drawn signature will often have tiny pooling marks where the forger hesitated or stopped to check their reference material. Authentic signatures have smooth, continuous ink flow, even if the signature itself is messy.
2. Tracing Marks (The Impression)
A common forgery technique on photographs involves tracing over an authentic signature with a stylus to create an indent, then going over that indent with a pen.
Hold the item at a sharp angle to a strong light source (raking light). If you see a physical indentation in the paper that extends *past* the end of the ink stroke, or diverges from the ink path, it is likely a traced forgery.
3. Anachronistic Ink
The Sharpie marker was invented in 1964. If you have a Babe Ruth signed baseball (died 1948) signed in thick, modern felt-tip marker, it is a forgery. Always cross-reference the era of the signer with the commercial availability of the writing instrument.
Tool: Magnification Simulator (Ink Bleed)
Adjust the magnification to see how live ink bridges paper fibers vs a printed reproduction.
Authentic Live Ink
Printed Fake (CMYK)
Notice how at high magnification, a printed fake reveals uniform dot patterns, while real ink sits organically in the fibers.
