C-

Investment Grade

⏳ Retired

The Heart Box, being a basic DUPLO set, is unlikely to see significant appreciation in value. Its primary appeal is as a starter set for young children. While retired, the set's widespread availability and the nature of DUPLO bricks mean it's unlikely to become a highly sought-after collectible. Investment potential is low, focusing instead on the educational and play value it provides.
