Autopen vs. Hand-Signed Autographs
A practical comparison of machine-signed and hand-signed autographs, and the other look-alikes worth knowing.
Published · 5 min read · By CollectorFish
The core difference
A hand-signed autograph is written by the person, so it carries the rhythm of a human hand: it speeds up on familiar strokes, varies in pressure and never repeats exactly. An autopen follows a stored pattern, so it moves at a mechanical pace and can produce identical signatures again and again.
What to compare
- Line quality: hand-signed lines usually taper as the pen speeds up and lifts; autopen lines tend to keep the same width and end abruptly.
- Pressure: a hand presses harder on some strokes than others; an autopen applies steady pressure.
- Flow: hand-signed curves are smooth at speed; autopen curves can show small tremors.
- Start and end points: autopen signatures may show small ink dots or blobs where the pen lowered and lifted.
- Repetition: two hand-signed examples are never identical; autopen examples from one pattern overlay almost perfectly.
Other signatures that aren’t hand-signed
- Stamped: an inked rubber stamp leaves flat, even ink, often with a faint outline or uneven edges, and no pen indentation.
- Preprinted: printed as part of the photo or card. Under magnification you see a printed dot pattern instead of continuous ink. See what a preprint autograph is.
- Secretarial: genuinely handwritten, but by an assistant or family member signing on the person’s behalf. These can be hard to spot without comparison to authentic examples.
Practical steps before you buy
Ask how the item was obtained, look closely at high-resolution photos, compare it with genuine examples from the same period and be careful with fan-mail and official-office items. For valuable pieces, a third-party opinion can help; see autograph authentication explained.

A preprinted signature is part of the print itself. It can look convincing in a frame, but it isn’t an autograph.
