Rim coining aligns the rim well enough on the hub. The alignment pins really didn't do much, which is why they were largely eliminated.
The coins on dual rims must 'nest.'
I've only seen the pins on rear hubs, to try to get the "technician" (policorrect speak for Tire Monkey, like "travel center" for Truck Stop) to get the inner and outer coined wheels into "nested" position.
Trivia: Our 1983 Ford E350 was interesting. Coined 16.5" wheels. So there were pins in the rear. If you looked carefully, you could see that every other nut sat deeper than its neighbor. The other trivia: The Left Rear Lugs were Left Hand Thread, but the Left Fronts were Right Hand. It paid to keep watch over the technicians to prevent chaos and damage.
In the 1984 chassis model year, the E350's got 16.5" hub piloted wheels, so swapping to 16" from later Fords was easy. We never switched.
