When collecting items, start by defining your focus. Choose a specific category, such as stamps, coins, or vintage toys, to make your collection meaningful and manageable. Research the history and value of your chosen items to enhance your understanding and appreciation. Next, establish a budget to avoid overspending. Attend local flea markets, antique shops, or online platforms like eBay to find items. Keep your collection organized by documenting each piece, including its condition and purchase details. This will help you track your collection's growth and value over time.
