# Mewtwo EX #164/162 — BREAKthrough

## Summary

A Secret Rare Mewtwo in the BREAKthrough run sat above the set's regular EX slots, and Mewtwo remains one of the most loved Gen I Pokémon, so demand has deep roots. Mitsuhiro Arita is among the franchise's most celebrated illustrators, which gives collectors a second reason to hunt this printing. The modelled guide sits at $218, up 8% over 30 days on 89 copies traded, with only 10 days of inventory on the board; the slab is the real edge, with PSA 10s at $13,400 and a 7% observed gem rate putting about $700 of expected profit per submission.
