# Lairon #37/109 — Ruby & Sapphire

## Summary

Lairon is the middle step of the Hoenn steel line, a Pokémon fans respect more as a bridge than a star. Mitsuhiro Arita, who illustrated the original Base Set Charizard, lends this uncommon a quiet pedigree, though it stays a modest mid-tier pull. At a $2.54 modelled guide, up 1% over 30 days on 14 copies traded, with 119 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.17 out of Twilight Masquerade; PSA does not split this card’s population by finish, so no gem rate can be read for it.
