# Dusk Mane Necrozma GX #SM102 — SM Black Star Promos

## Summary

Dusk Mane Necrozma GX is a Sun and Moon era promo, so it came through a product tie-in instead of a booster pack, which suits completionists more than pack hunters. Necrozma holds a prominent place among Gen VII fans, and its Metal GX attacks gave it some curiosity value in play. The modelled guide sits at $6.30, down 1% over 30 days on 21 copies traded, with only 15 days of inventory on the board; PSA 10s at $450 are only 71 times raw with a 17% gem rate, so grading barely breaks even, and the slabbed population is growing 3% a month, faster than 93% of tracked cards.
