Some very common methods get repeated in the threads here when people ask for help in trying to authenticate a signature. The formation of certain letters, breaks between specific letters, shakiness or evidence of an unsteady hand. Does anyone have any unique observation types that aid them in their assessments?

For me I find one of the most useful, and surprisingly simple methods is to turn the signature and analyze it upside down against a known genuine. Often times our brains get into a habit of looking at and processing data a certain way and we’re never aware of it. This breaks your brain’s habits and lets you see the signature in a completely different light. Nuances that were not noticed before in a signature suddenly jump off the page at you.
