Interesting but I'm not seeing die polishing lines going in the direction mentioned. They seem to be going NW-SE above and below the 1, in the first image.
(I do see a raised line/die gouge inside the 4 that goes NE-SW though.)
Is there really a short, raised "nub" at the end of the cross bar of the 4, like me eyes are showing me?

We need to consume them regularly to thrive and grow.
