Why Do We Have ‘Money’ in Different Shapes and Sizes?

Money isn’t just about numbers, it’s also about how it looks and feels. Coins come in different shapes and sizes so we can tell them apart by touch or sight, especially when we’re in a hurry. Some coins are big and round, like quarters; others are small and square, like some nickels. This helps people know which coin is worth more without counting, it’s like having a special code for each one!
