In following paper some aspects of tossed coin dynamics are presented. Firstly: one-, two-, and three-dimensional coin models are presented. More general case of nonsymmetric or nonhomogenous coin is described. It is assumed that the coin is released above a plain floor. Free fall of the coin as well as the coin motion including air resistance forces and moments are analysed. Some results of numerical solution simulations are shown.
