As for die pressing/struck: During the 3rd reich period and before,,commercial firms all had at least one die cutter [and apprentice] on staff. They all had a die room where the masters were kept sometimes under lock and key. Working dies were exact, exact duplicates of the master die.. when a worker got worn, or broke,,another was made from the Master.
IF there was a flaw it could not be repaired as the Master was super hardened,,and the worker would soon fail at the spot that was tried to be corrected. So every HR would be exactly the same as it came out of the die. Very little if any correction would be needed. Now IF you wanted to do some embellishing yes that was possible. But the photo above of the Swas panel,,one ring has a cut in it and another doesn't and the cut does not look hand done..
