|A square coin with edge alignment|
On an edge-aligned coin, the design is lined up with one of the coin's edges so that when the coin is held right-side up it looks like a square.
|A square coin with corner alignment|
On a corner-aligned coin, the design is lined up with one of the coin's corners so that when held right-side up the coin looks more like a diamond (though it's really just a square standing on its point).
In the last century, several different countries have used square coins. These are the countries that I am aware of that have had square coins, but this is probably not complete.
