Trading cards are small cardboard sheets typically depicting images, statistics, and other information related to various subjects such as sports figures, comic book characters, and historical events. These collectible items often come in sets, with each card possessing unique characteristics that can make them highly sought after by enthusiasts and investors alike. The allure of trading cards lies in their ability to capture the essence of a given subject in a compact and visually appealing format, as well as the potential for increased value over time due to rarity or demand. As such, trading cards often undergo processes like varnishing to enhance their appearance and durability, thereby further increasing their appeal to collectors.
