J P M Posted May 10 Share Posted May 10 It looks like die deterioration doubling from a worn-out die. Sandon and Coinbuf 2 Link to comment Share on other sites More sharing options...
Coinbuf Posted May 10 Share Posted May 10 (edited) Yep JP is correct this is die erosion. As a die wears with use the edges of the letters and devices start to become rounded. That allows some of the metal that would be contained by those edges to squeeze out at the time the coin is struck. Which gives this appearance.
