# Nidoking #45/114 — Steam Siege

## Summary

Nidoking is a Gen I stalwart whose Ability rewarded building around its Nidoqueen partner, and a plain Rare in Steam Siege sat in the mid-tier of the pull, never a chase slot. Mina Nakai is an established name among Pokémon illustrators, so completionists of the Poison-type line tend to keep it. The modelled guide sits at $0.78 with 47 copies traded in 30 days, and the tape reads as a floor forming near the lows; a PSA 10 guides at $70, 90 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
