Selected title: Friction
Explanation: A frontiersman might rub two sticks together and the result is a fire. The rubbing of a coin can result in a wear on its surface. Typically, friction causes various degrees of noticeable wear and results in lowering the desire (and value) of a coin. Friction can be caused by a coin sliding in a holder, coin drawer, or even by a good intending collector who tries to 'clean' the coin
