17. Copper

There is also another 863 copper coins stacked about the room in varying heights. This is actually a cruel trap set by the Gnomes who inhabit the dungeon the players are pillaging. When the gold coins touch any other coins after 1 day the coins touched will turn into copper coins.

The players won’t find any traps about and only know something is up if they happen to use detect magic; even still they will only know that the coins are magic until they have time to research it. If the players toss the coins with the rest of their loot the coins turn everything into coppers.
