Looks like a cud

I would say a die chip.

Thanks guys, thats what I thought. Still dont know what a cud is.

cud
An area of a coin struck by a die that has a complete break across part of its surface. A cud may be either a retained cud, where the faulty piece of the die is still in place, or a full cud, where the piece of the die has fallen away. Retained cuds usually have dentil detail if on the edge, while full cuds do not.
