Trump fraudulent coins

Exploration Stage: Secret Room
From: Cardsharp
Description: If I had known that the artifact of the Goddess of Autumn would shatter at the slightest touch, I would not have tried to steal it! Now that this has happened, I must pass the test of virtue and beg her forgiveness. Will you lend me a hand?
Completed: This ring of generosity was given to me by a wandering musician. I put some coins in his case when he was playing in the park.
