Authentication notes

Every Pokémon card is checked against known-genuine references: card stock and light-blocking layer, holo foil texture and pattern for that specific era, font and color accuracy on HP/energy symbols, and card-back print quality. First edition WOTC holos and modern alt-art chase cards get extra magnifier-level scrutiny before pricing.

No guesswork

How we get to your offer

We pull the live market comp for Mewtwo [Inverted Stamp Error] on Pokémon, then apply the same locked rates we use on every trade-in: 85% of comp in cash, or 100% in store credit. No lowball guesswork, no per-item haggling. The comp is the only input, and the math is the same for a common card and a grail.
