The 2 - penny back/dime back on the other side I looked up. It said people did this on train tracks by using 2 coins. When I looked at examples the writing was distorted and the coins were distorted shape. These are perfect condition, shape, markings . They are thiner than they should be and 1 has the scored edging and sounds like a real coin. The other one has smooth edge and does not sound like a real coin.
