Children's Currency refers to the informal system of value that children create among themselves, often based on items like toys, stickers, or even favors. This system allows children to trade and negotiate, helping them learn important social skills such as sharing, cooperation, and conflict resolution. In this context, items like trading cards or marbles can hold significant value, depending on their popularity or rarity. Children's Currency is not about money; instead, it emphasizes the importance of relationships and interactions, fostering a sense of community and understanding among peers.
