Overlord,
This is about how both sides of a coin are positioned against each other.
Most modern coins are either in medal alignment (↑↑) or coin alignment (↑↓).
For some coins varieties exist and some of these are rare and expensive.
Also, sometimes it happens that a die isn't properly fixed in the minting press so it starts rotating during the minting process. The coins minted are having an increasing axis rotation. An example is shown.

And no, I won't ask how many coins are still made in this "coin" alignment nowadays. ;D
