If you ever happen to find yourself fortunate enough to find yourself in the possession of a story coin, be comforted in the knowledge that it can be exchanged for a story. If you ever see me or another story-teller that accepts story coins, you can hand over the coin and thus be told a story.
Here is an example of such a transaction:
You see a story-teller that is known to accept story coins, and you tug on their cloak or tap on their shoulder and say:
“Excuse me, sir or madam, I have here a story coin, and I would like to hear a story.”
At this point they will accept your coin, and tell you a story.
The story-teller may ask you what kind of story you would like to hear, so it is a good idea to have considered this beforehand.
