Professor Minerva McGonagall, Dark Green Robes, Hat, and Cape

Professor McGonagall in her dark green robes is a highly desirable minifigure for LEGO Harry Potter collectors. The character's importance in the series, combined with the relatively limited number of sets in which this particular version appears, makes it a sought-after piece. The dark green robes are a classic representation of her Hogwarts attire.

Collectors will pay close attention to the condition of the fabric cape, hat, and torso print, as these are key indicators of value. A McGonagall minifigure with pristine details and no fading will command a higher price on the secondary market. Also, the head is unique to this minifigure.

This Professor McGonagall minifigure is moderately rare, appearing in only one set, the 2010 Hogwarts Castle (4842-1). While the set itself was fairly widely available, the single appearance of this specific minifigure contributes to its collectibility. Given the age of the set, finding this minifigure in excellent condition can be challenging, further increasing its rarity.

The investment potential for this Professor McGonagall minifigure is good. As a key character from the extremely popular Harry Potter series, demand remains strong among collectors. The retirement of the Hogwarts Castle set further boosts its value. Comparable Harry Potter minifigures from similar-sized sets have shown consistent appreciation over time, suggesting this McGonagall minifigure will likely follow a similar trend.
