<p>[QUOTE="coinguy-matthew, post: 1623067, member: 35762"]The source of the scratches is from the annealing process and subsequent washing we already determined that with a call to a former mint employee or you can read about it on the ikegroup.com. The struck half of the off center coin is smooth and flat because the pressure from the strike makes the metal flow and essentially melts the surface of the coin and allows it to take on the shape of the die. The article i posted describes the minting of gold and silver business strike coins.[/QUOTE]</p><p><br /></p>
