Investment Grade

⏳ Current release

The UNEARTHED Challenge Set holds moderate investment potential due to its educational focus and association with the FIRST LEGO League. Its value will likely be driven by its utility as a learning tool and demand within the educational community. Unlike licensed sets, its appeal is niche, making it less susceptible to broad collector interest. However, if the FIRST LEGO League continues to grow, demand for these sets could increase, especially if retired. The large piece count may also make it desirable for parts.
