I thought it was a strike-through at first, but with all the die cracks, it must be a die problem. You can play tic-tac-toe between the cracks. Probably latest stage - die crack unlisted by Haxby from leaf 8 to 9.
That's a great coin TerryT! I agree with Dan that the die is collapsing from all of the cracks. The crack from leaf 8-9 does make it a later state than what is in the catalog. I haven't seen one that late before. I love those late state coins! Thanks for sharing it.
