At the end of the week, each of them had 4 pennies given to them by Grandpa Nikolai.
25 penny was 1 silver, and 50 silver was 1 gold. That's how currency works, at least for this kingdom.
On the penny coin was a symbol of the Azuvell Kingdom, wheat and a dagger crossing each other on top of the shield. With Edes, God of nature and harvest, on the other side of it.
The grand bishop and Kretia, Goddess Of The Hunt, were on the silver coin. As for the gold coin, there was King Gremold Duan, who had previously become king of this kingdom. On the other side was Atheus, the goddess of magic, who was the main god of this kingdom.
Takeuchi is guessing that if the current king died, he would grave into gold coin. He had not yet seen how silver and gold coin, but it was enough for him to see what a penny looked like.
Not only a penny at the end of the week, Nikolai gave them a holiday.
Usually, he would save some of the penny and celebrate it by buying beer at the bar in the town.
