Tim Duncan, San Antonio Spurs #21

The Tim Duncan minifigure is a must-have for LEGO NBA collectors and fans of the San Antonio Spurs. As a representation of one of basketball's all-time greats, this minifigure carries significant appeal beyond just LEGO enthusiasts. Its unique molded head and detailed jersey print make it instantly recognizable.

Condition is key for this minifigure. Collectors will seek versions with minimal wear to the printing on the torso and head. Given its age, finding one in pristine condition can be a challenge, adding to its desirability.

This Tim Duncan minifigure is relatively rare due to its exclusive appearance in a single, now-retired set: the NBA Collectors #1 (3560-1) from 2003. This limited availability makes it harder to find than minifigures that appeared in multiple sets or were produced over several years.

As a licensed theme from the early 2000s, the NBA line had a shorter production run compared to evergreen themes like City or Star Wars. This further contributes to the limited supply of this specific minifigure on the aftermarket.

The Tim Duncan minifigure has good investment potential due to its rarity, character recognition, and the increasing interest in vintage LEGO sports memorabilia. As the set it came in has been retired for over two decades, demand from both LEGO collectors and basketball fans can drive up its value.

While not as high-value as some exclusive Star Wars or Marvel minifigures, its niche appeal and limited availability suggest a steady appreciation in value, particularly for versions in excellent condition. Prices may fluctuate based on condition and completeness of the figure with its accessories.
