Wondrous Item, uncommon
This small copper coin has no “heads” side. Instead, both sides are “tails”. When you give the coin to an unsuspecting victim, the victim must make a DC 15 Wisdom (Perception) check or accept the coin as true currency. If the coin is accepted, you can use a reaction to cause the coin’s recipient to fail a single saving throw at some point in the next 24 hours. The coin magically returns to your possession at the end of this 24 hour period.
