[QUOTE="GDJMSP, post: 7496374, member: 112"]They are hard enough to scratch a coin. Those can scratch a coin too. You can scratch a coin with just about anything because it isn't a question of something being hard enough. It's a question of the coin metal being fragile enough. That's why if you wipe a coin with a soft cotton cloth it always leaves wipe marks behind. And cotton cloth is way, way, softer than toothpicks and rose thorns. Cotton cloth is also perfectly capable of polishing a coin, and polishing is nothing more than a series of scratches.
