Is this LEGO set a good investment?
“Over that last few years Mosasaurus has been a particularly good investment for Dinosaurs collectors with an annualized growth of upwards of 9.2% per year. However, there is market indication that the set will experience a slight annual growth decrease in the coming years, but this should be only by a few percentage points at most. When compared to the vast majority of set in the Dinosaurs theme, this set is still an excellent investment for collectors.”
Review brought to you by BrickEconomy Bot
“The LEGO Dinosaur set from 2001, remembered for its articulation and imposing jaws, offers a blend of nostalgia and playability, particularly noted for its high-quality printing and detailed design. While not the most anatomically accurate, its charm lies in the blocky,... More simplistic aesthetic typical of early LEGO sets, which many find appealing. The set's versatility is enhanced by the inclusion of spare parts for alternate prehistoric builds, though the specialized pieces may limit their use in other contexts.”

The world has perhaps never seen a predator larger than the Mosasaurus! The size of a small seas feared absolutely nothing. Turn the giant Mosasaurus into three other distinctive and attractive dinosaur models — the set includes extra building instructions for Iguanodon, Postosuchus and Dimetrodon.
