SpongeBob Trading Card Boxes Could Be Worth Hundreds or Even Thousands in 25 Years. Sealed 2025 Topps Chrome SpongeBob SquarePants 25th Anniversary blaster boxes are already gaining attention among collectors, with prices rising from their original $39.99 retail price to over $100 on the secondary market shortly after release. As a major nostalgia-driven franchise that has remained popular for more than 25 years, SpongeBob SquarePants has the kind of cultural staying power that can help collectibles grow in value over time. While retail boxes are typically produced in large quantities, long-term scarcity and continued fan demand could push sealed boxes into the $500–$1,000 range over the next 25 years, with the possibility of even higher values if the trading card market continues to expand and rare chase cards keep collectors hunting sealed products.
