I've noticed that people here use strange currency.
Spruce looks at the gold, silver, and copper coins in your hands with a slight frown. He then takes out an old coin to show you.
You have an unusual aura. If you go to the Summer Festival, you'll be able to earn rewards like this.
But I haven't seen anyone else with luck like yours.
If you collect 60 of them and want someone to take them off your hands, bring them my way.
I'll give them to other residents who want to experience the festival.
