Description
You show the coin changer empty from all sides. You say a short spell and you have conjured a coin. But this little tool is known as the coin changer. So you place, for example, a Danish 1 krone in the small compartment in the holster. And as soon as you say a spell, it has turned into a 50 Euro Cent.
Of course, you can also do magic with other coins that match the size of a Danish 1 Krone. Or conjure a button into a coin.
