# Ultra Necrozma #SM165 — SM Black Star Promos

## Summary

Ultra Necrozma is a Black Star promo, so it was never pulled from a pack, and that gives it a modest but steady pull among Sun & Moon-era completists. Necrozma carries real Ultra Beast and box-legendary clout with fans, and Shin Nagasawa is a respected name among illustrators. The modelled guide sits at $4.80, up 6% over 30 days on 9 copies traded, with 164 days of inventory on the board; a PSA 10 guides at $57, 12 times raw, but a 5% gem rate against $85 of fees makes grading a losing trade.
