Nanna

Nanna, from the Hidden Side theme, is a desirable minifigure due to her unique character design and the theme's dedicated fanbase. Her distinctive hairpiece and the detailed printing on her torso, featuring a safety vest and layered clothing, make her visually appealing. As a civilian character within the ghost-hunting narrative, she adds depth to the Hidden Side world.

Collectors value minifigures that contribute to completing a theme's cast, and Nanna is a key part of the supporting characters in the Hidden Side universe. The condition of the minifigure, especially the printed details, will be important for collectors.

Nanna appears in only one set, the Paranormal Intercept Bus 3000, which was retired. This limited availability inherently increases her rarity compared to minifigures appearing in multiple sets. While not a limited-edition or promotional minifigure, her single set appearance makes her harder to acquire on the aftermarket, particularly in excellent condition.

As a character from a retired LEGO theme, Nanna has the potential to appreciate in value over time. The Hidden Side theme had a unique appeal with its augmented reality features, attracting a dedicated collector base. The retirement of the theme means no new sets will be produced, potentially driving up the prices of existing minifigures like Nanna. While not a top-tier investment, she is a worthwhile addition for collectors focusing on complete themes or unique minifigure designs.
