# Vileplume #H31 — Aquapolis

## Summary

Vileplume is a Kantō-era Grass Stage 2 with a quiet but steady following among Gen I loyalists, and Kyoko Umemoto is a name collectors of the early 2000s associate with soft, painterly work. Aquapolis holos carry extra weight because the set sits at the tail end of the WOTC run. At a $142 modelled guide, up 15% over 30 days on 6 copies traded, with 121 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.17 out of Phantasmal Flames; the slab is the real edge, with PSA 10s at $6,500 and a 7% observed gem rate putting about $75 of expected profit per submission.
