Measure it instead of squinting at it
NumismaLab is a microscope bench for coins: a calibrated scale, measured relief from a moving lamp, and tools that say what they measured rather than handing you a verdict.
This is a reference, not an attribution. It narrows the field and names what each die is identified by; deciding that a coin is one of them is done with the coin under a lens, by a person, against the markers. Nothing here grades a coin or says it is genuine, and the wording is written from structured facts rather than copied from any catalog.
