City

LEGO City represents one of the most enduring and broadly appealing themes in the collector's market, tracing its roots back to the 1955 LEGO System in Play and evolving continuously for over 60 years. The theme's remarkable longevity and mass-market appeal create steady but modest investment returns compared to more specialized collectors' themes, with investment value varying significantly within the theme based on factors like included minifigures, licensing details, and collector demand. City sets typically see price increases after retirement, though they generally command lower resale premiums than limited-edition themes like Star Wars or Creator Expert modulars.
