The obv is showing die cracks not die breaks. Difference being that on die breaks a piece of the die has actually broken away leaving a raised lump on the coin. On the reverse the tops of the D in UNITED and the first S in STATES are examples of hub breaks. Those parts of the letters on the raised hub that was used to make the working die were broken away. So no cavity was impressed into the die and the coins struck from the die have the tops of the letters missing.
