Flipping guide
Flipping cards is one skill repeated over and over: find a listing priced below what the same card recently sold for, buy it, and resell at the comp. This guide walks the exact workflow — and how Find Gem Cards A.I. automates the slow parts across Pokémon and other TCG markets.
Most underpriced Pokémon cards are listed by non-collectors: estate lots, bulk binders, blurry photos and titles missing the set code. Those listings never surface in normal searches, which is exactly why they sell under market.
Find Gem Cards A.I. sweeps live web listings, parses the set, number and parallel out of messy titles, then cross-checks each one against recent sold comps for the same card in the same condition.
Deal score blends three things: ROI versus sold comps, liquidity (how often that card actually sells), and rarity. A 92 on a $40 card beats a 61 on a $400 card — high score means the market has repeatedly paid more for that exact card.
Resale upside is sold comp minus ask minus fees. Budget roughly 13% marketplace and payment fees plus shipping. A $60 card with a $95 comp is about a $22 profit, not $35 — the app already subtracts this for you.
Flip raw when the spread is under ~$100 or the card has visible wear. Send to grading only when a PSA 10 comp is at least 4x the raw comp and centering, corners and surface look clean under angled light.
Flippers make money on velocity, not on holding. List at or slightly under the median sold comp, use the full set name and card number in the title, and photograph all four corners.
| Category | What to look for | Why it's mispriced |
|---|---|---|
| Modern chase cards | Alt-arts, special illustration rares, full-art trainers | Sealed-product hype prices swing weekly, so mispriced singles appear constantly |
| Vintage holos | Base Set, Jungle, Fossil, Neo holos | Condition-sensitive — sellers who list 'played' often undervalue a near-mint copy |
| Graded arbitrage | PSA/BGS slabs listed below slab comps | Slab comps are precise, so mispricing is easy to verify in seconds |
| Bulk lots | Binder and collection lots with one visible chase card | Lot price is often below the single card sitting in the photo |
profit = sold comp − ask price − (comp × ~0.13 fees) − shipping
Resale upside in the app is this number, and deal score is that profit weighted by how reliably the card sells. Pair them: high upside with a low score is a card that may sit for months.
Yes, but the margin has moved from sealed product to underpriced singles. The edge now comes from finding badly listed cards faster than other buyers, which is what automated scanning solves.
You can start under $100 flipping $10–$30 singles. Small, liquid cards turn over quickly and teach you comps without tying up capital.
80+ is a strong buy signal, 60–79 is worth a manual comp check, and below 60 usually means thin margin or a card that rarely sells.
The same method applies to Magic: The Gathering, Lorcana, Yu-Gi-Oh! and sports cards — any market with public sold comps.
