Which authentication example involves comparing a handwriting sample with an authenticated specimen?

• A. Rule 901. (b)(2)
• B. Rule 901. (b)(3)
• C. Rule 901. (b)(4)
• D. Rule 901. (b)(1)

Answer: (B)

Authenticating handwriting through distinctive characteristics is about tying the disputed writing to a known specimen by examining the unique patterns in the handwriting. When you have a handwriting sample and an authenticated exemplar, you look for consistent features—how letters are formed, slant, spacing, pressure, and overall rhythm—that uniquely identify the writer. If these features line up between the sample and the authenticated specimen, authentication is established under the rule that allows using appearance and distinctive characteristics in conjunction with the circumstances.

The approach is more than a general identification by a witness or a simple lay opinion; it focuses on the tangible, distinctive handwriting features that persist across documents. So comparing the handwriting to a verified specimen to confirm authorship exemplifies using distinctive characteristics to authenticate.
