Checking the markers is the work

Every marker above is something you have to find on an actual coin, at an actual magnification. CoinScope Pro puts a real scale on the photograph so a spread is a number you can compare, and refuses to answer when the evidence will not carry it.

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.
