1879 penny.

[King Kenny]

I have just got this 1879 penny and I noticed a connecting spar on the O of ONE. I first thought it was a die crack, but it seems too wide for that. Any ideas?

[jelida]

Definitely a die crack. As metal is lost from the sides of the crack the flaw on the coin becomes steadily wider until the die breaks or is withdrawn from use.

Thanks Jerry. That makes a lot of sense. I have not studied die cracks much, a lot to learn.
