Bullshit. Different parts of the coin surface have different friction forces, so it is impossible to have such an effect. If the surface friction coefficient is exactly the same, the friction force is different because of the different pressure of each part of the coin on the paper. The resultant force of friction on the surface of each micro-element just makes the center of gravity move like the edge of a paper, and it will stand up after continuous pulling.
