1973 D Penny Possibly A Die Clash

error-ref.com explain Die Clash. I do not see traces here.

just a gouge on the fields on the obverse, and damage on the reverse.

Closer photos would help us see exactly what's going on with the B. Overall I agree, post mint damage.

Coins banging into each other don't make them clashed. It is dies clashing together (without a planchet between them) that creates a clashed die coin. The pattern will look like an outline of the central devices:



These will look like the mirrored devices but slightly raised above the fields/design:

Note how the devices are raised above the fields and design areas? This is slight. But damage to a coin will be incuse marks, not raised above the fields/design on these coins.







These will remain on the dies until they are polished off of the dies. This reduction alters the height of the devices/design on the die, affecting the coins struck with these dies. The damage affects both dies.
