LEGO sets often increase in value after they are retired, creating a secondary market where collectors pay premiums. The appreciation is driven by scarcity, thematic popularity, and the condition of the set.
To quantify this growth, we compare the original retail price with the current market price. By expressing the difference as a percentage of the original cost, we obtain a clear metric of investment performance.
Collectors can also factor in the time elapsed since retirement to assess annualized returns. This deeper analysis helps decide whether a set is a hobby purchase or a financial asset.
