Doubling on branches
24 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 branches 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.
