Unfortunately, your dime is just damaged. Modern US coinage utilizes a three layer "sandwich" composition for the dime, quarter, and half dollar- outer layers of cupronickel alloy with a core of pure copper. The damage on your coin is typically attributed to being trapped in a commercial clothes dryer for a long period of time. The repeated tumbling and banging action against the steel dryer drum smooths out the reeded edge and rolls it inward, resulting in a rim that looks thicker than that of a normal coin but with a smaller diameter.
