Stamps
A stamp collection is a way for kids to track time and see how the world changes. Stamps are constantly in flux with historic origins. If you encourage your child to start a collection now and he continues to collect throughout his life, his collection will be financially rewarding if he chooses to sell in the future. Beyond financial rewards, stamp collecting also teaches about history and culture, as many stamps commemorate historical figures.
Rocks
A rock collection fosters the creativity within every kid. The endless supply of metamorphic, sedimentary and igneous rocks allows kids to pick and choose from millions of rocks that have different textures, colors, shapes and sizes. Rocks also teach the importance of geology and understanding properties of Earth's minerals. Some of the best places to find rare or unique rocks are dried riverbeds and along hiking trails.
Coins
Coin collecting, also known as numismatics, is a way for kids to not only save money but also explore different cultures. If your family frequently travels outside the country, he can learn about the different figures on coins and understand the value of money in a worldwide economy. Over time, a coin collection increases its value like stamps, which creates a valuable investment if started at a young age.
Trading Cards
Kids can collect a wide range of cards from sports to fantasy cards. Sports card collections give kids a chance to keep up with favorite players in sports that they like, such as baseball and basketball. Fantasy cards also celebrate characters for favorite card games like "Magic the Gathering." Kids also learn how to organize cards into display portfolios and maintain the quality of the card by preserving the paper.
