This question is about the case of rolling motion, as in, for instance, rolling down an incline. So you see a coin rolling over, say, the floor of a corridor, and it just keeps going.
Another case is the one of a coin that isn't going anywhere; it is made to spin in place.
Those are distinct cases, yet John Rennie and Qmechanic have closed the question about a rolling coin, labeling it as duplicate of the spinning-in-place case.
I don't have enough reputation points yet to submit this for reversal of the mislabeling, so I'm reporting it here.
(I noticed the mislabeling because I had written an answer)
