It is impossible for an single strike off center coin to have reeding. An off center error occurs when a planchet is misfed to the dies and it is not centered when struck. The planchet is normally held between the dies with a collar(the third die). The collar defines the diameter of a coin and also imparts the reeding during striking. Off center= no collar, no collar= no reeding. As for falling into "gearing", the presses are hydraulic so there is very little in the way of gears on an operating press. However, I strongly suspect that any coin that fell into such a place would be mangled enough that it would never make it into circulation. Of course, we would need to see pictures to determine exactly what is going on with your coin.
