AUTHENTICATION PROCESS
The authentication process involves examining the signature to see how it compares to known authentic examples. Key factors used to determine authenticity include consistency, or lack thereof, in various characteristics of the signature, such as; letter formation, size, slant, spacing, style, pen pressure, and fluency. While everyone writes their name a little differently each time, a skilled authenticator can differentiate that from a non-authentic signature. Other factors that play a role in authentication are: (1) knowledge of how a signature has changed over time; (2) the age of the ink; (3) knowing where on an item a subject is inclined to sign it; and (4) the type of item signed relative to the subject’s date of death.
