My dear old Grandpa said that if you think, think and think some more, then you've probably over thunk it!! Them old mint workers are probably looking down at us and really getting a good chuckle out of our modern day logic being applied to coins that were minted in their day, because the only thing that was important to them was making quota! Back then it was just a coin and a job, they never dreamed that people would someday have enough idle time to view those same coins with a loupe or dinolite.
