Trickster’s Coin

Wondrous item, common

Price: 80-200 gp | low sentimentality

This gold coin has no markings on it but is otherwise a real gold coin worth the equivalent of 1 gp when used for trade. Once a day, anyone can squeeze the coin twice in the span of 1 second to activate the coin. An activated coin returns to the hand of whoever activated it at dawn the next day. There is no way to detect if the coin has been activated, and the coin can’t be deactivated once activated. Attempts to activate an already activated coin have no effect.

Paid

The coin changes shape to bear the markings of the most common currency that match its value in its surrounding area.

Overpaid

The coin is now a platinum coin worth 1 pp, with all its other properties remaining the same, including its Paid properties.
