Drilled holes in old coins. Which side did they start on?
First, just getting back into coins after many decades away and with finding this forum I have learned an amazing amount about coins, thanks!
Question is when old coins where drilled many years ago, which side did they start on? The crude holes show an expansion on one side as if the metal was "pushed" aside while making the hole. I'm guessing that's the exit side, but still a guess.
There's so much knowledge in this forum I am sure some people know the answer. TIA!
