Yes, you can see the 4 better under a 10x loupe with the correct lighting. To the naked eye, it’s invisible.
Thanks for the photo, Larry. This plainly shows what I meant by the 1 being equally spaced between the 9 and the 4.
This is a cool image that one of our past members worked up. It shows the known placements of the mint mark.
Also notice the size of the second 1 is not the same size as the first 1 as it is on the genuine coin.
