<p>[QUOTE="cpm9ball, post: 1538619, member: 24633"]It could be a retained dropped element. What happens is grease and debris fill the incused letter on the die. Continual striking of coins compacts it to great hardness. When it falls away from the die and the next planchet is struck, it is embedded into the coin. Sometimes it will fall away on its own, but other times it remains embedded in the coin.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
