A promotional release tied to the Wonders of the Natural World series, Northern Lights Diorama (40785) was retired in 2025 and its short run and series cohesion leave sealed copies relatively scarce, while the lack of exclusive minifigures and non-licensed subject suggest steadier, moderate post-retirement performance rather than sharp spikes.
