# Meganium #18/165 — Expedition Base Set

## Summary

Meganium is the Johto starter that never quite got its due, and fans of the Chikorita line still gravitate to anything holographic. Its Soothing Aroma gave it a niche healing role, and as an Expedition holo it sits among the set's big pulls. The modelled guide sits at $180, flat over 30 days on 2 copies traded, with 212 days of inventory on the board; a CGC 10 brings $10,950, 61 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
