# Probopass #55/114 — Steam Siege

## Summary

Probopass is a Sinnoh-era Fighting type with a devoted cult following, the magnet-nosed mustache fans adore for sheer weirdness. In Steam Siege a plain Rare sat mid-tier, a binder pull rather than a chase, so demand rests on Gen IV affection and MAHOU's name. A $0.27 modelled guide with 3 copies traded in 30 days says bulk, and the economics stop there: a PSA 10 guides at $32, 120 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it, and the same card plays for $0.04 out of Perfect Order.
