Professor Minerva McGonagall, Dark Green Robes, Black Hat (Single Sided Head)

Professor McGonagall is a beloved character in the Harry Potter universe, and this minifigure is a desirable addition to any LEGO Harry Potter collection. Collectors appreciate having representations of key characters in different outfits and contexts, and this version from the Advent Calendar provides a unique opportunity to own a McGonagall minifigure that's slightly different from the standard versions.

The dark green robes and black hat are iconic elements of her Hogwarts professor attire, and the single-sided head print gives her a classic LEGO minifigure charm. The condition of the minifigure, especially the printed torso and head, is crucial for collectors seeking to maintain or increase its value.

This Professor McGonagall minifigure is relatively accessible due to its inclusion in the Harry Potter Advent Calendar 2019. While Advent Calendar minifigures are produced in larger quantities than those in exclusive sets, the retirement of the set has started to limit the availability of this particular version on the aftermarket. It's not a super rare minifigure, but it's also not one that is constantly available, giving it a moderate level of scarcity.

While not the rarest Harry Potter minifigure, this Professor McGonagall has some investment potential. The Harry Potter theme remains extremely popular, and demand for key characters like McGonagall will likely remain strong. The retirement of the Advent Calendar set it came in adds to its appeal. However, the investment potential is moderate compared to minifigures from exclusive or limited-edition sets. Monitor the aftermarket prices and consider the overall condition to maximize potential returns.
