Doubling on logs # 9
9 listed varieties show doubling here, across several series and dates. That is worth knowing before you get excited about one coin: a device that doubles often is a device where doubling is common, and where machine doubling imitates it most convincingly.

The same device, coin after coin
Doubling on logs # 9 looks similar across dozens of varieties, which is exactly why eyeballing it misleads. Measure the displacement instead and the differences stop being a matter of opinion.
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.
