The Worm Gear Pack, while small, has potential as a collectible due to its age and educational value. Its limited piece count doesn't make it a high-value target for investors, but its rarity as a complete, unopened set could drive up its value over time. Theme popularity and educational appeal contribute to its potential, but it's not a high-return investment.
