The three requirments below would apply to the unc versions of modern
commems. I am under the impression that they prepare the dies the same
then sand blast them with fine granuals to give them the matte finish.
So technically it costs more to make the UNC versions that the proofs.
The UNC Marines dollars is no doubt a matte proof.

Now another possibility would be for the dies not to be prepared as
well but say 90% as good then the flaws are covered by the
sandblasting.

No. By definition, a proof coin must be (MUST be)
1. struck multiple times.

2. from specially prepared dies

3. on specially prepared planchets.
