Common Pokemon TCG market mistakes (and fixes)

Most expensive Pokemon TCG mistakes are boring: bad identity matching, stale comps, and fee blindness. Fix those before hunting exotic arbitrage.

Mistake: comparing different assets

Fix: verify language, set code, number, and grade every time. If any field differs, prices are not comparable.

Mistake: trusting one outlier sale

Fix: prefer a cluster of recent sales over a single spike. Outliers happen from bidding wars, mislists, and thin nights.

Mistake: ignoring total cost

Fix: build a quick landed-cost habit — price + shipping + fees + FX. If the spread dies after that, pass.

Mistake: buying every top riser

Fix: treat risers as research queues. Many already moved. Your edge, if any, is in misunderstood cards still mispriced after friction — not in copying yesterday’s leaderboard.

Mistake: no exit plan

Fix: decide where you would sell before you buy. If you cannot name the venue and likely fees, you are collecting by accident while calling it investing.
