"Coining" is the raised area around the lugnut holes, and is alternated from the front to backside of the wheel.
This coining mates into the alternate recesses on each side of the wheel, front and backside.
This machining procedure is designed to eliminate wheel "walk" where the wheels meet, and is also used, to a degree, to align the wheels more squarely to each other.

Mr Nixon is correct.
Coined wheels were common for a good number of years until the industry finally discovered that the "coins" were cause for about 95% of wheel cracks and complete center break-outs.
Most of these problems are common with big, heavily-loaded, trucks, such as dump-trucks, milk-trucks, and the like.
Wheel cracking also occurs on ton-sized trucks; most just never load them enough for it to be a problem.
When it was found that the Chevy/GM flat-faced design of DRW wheels seemed to never crack, Ford started using them in 1985 and Dodge in 1994.
When they went with the flat-faced design, they also started making them hub-centric, or hub-pilot if you prefer.
