Magic Coin

Jayden is from poor family. Everyday, Jayden can only bring one piece of biscuit to school. The biscuit is for his breakfast & lunch.

One day, on the way to school, there is one beggar comes to Jayden, "could you please give me your biscuit?"

"How does he know I have biscuit?" thinks Jayden. Nevertheless, Jayden still gives the beggar his biscuit. In return, the beggar gives him a 50 cent coin.

"Why doesn't he buy biscuit with this coin?" thinks Jayden again, but he doesn't say anything and just goes to school.

"It is a magic coin!" shouts the beggar to Jayden before he disappears into the crowd.

After coming back to school, Jayden takes out his coin. "How magic is this coin?" He tries to shake it, throw it, rinse it, heat it, but nothing happens to the coin.

"Maybe it will duplicate," thinks Jayden. But the next morning when he wakes up, there is still only one coin on the table.

Jayden is tired of figuring out the coin, so he just puts it aside.
