How HoloScope prices graded Pokémon cards
A price is only useful for the exact card it belongs to. So the first job is working out what a listing really is, and the second is finding sales that truly compare.
OPEN THE TERMINALStep one: lock the identity
HoloScope matches card name, number, set, printing, language, year, edition, variant, grader and grade. Shadowless, First Edition, reverse holo, promo stamps and deck products stay separate, and so do Traditional and Simplified Chinese printings. When a card cannot be matched safely, it does not get a price.
Step two: build the grade lane
Completed sales are grouped by comparable card, grader and grade. A BGS Pristine 10 and a BGS 10 are separate markets, and a PSA 10 is not a CGC 10. Without enough evidence in the exact lane, HoloScope does not borrow a value from another grade.
Step three: weigh the sales
- Recent sales count for more. Fast markets update quickly, and thin markets keep older evidence for longer.
- Isolated spikes, mismatched sales and unusual trades are pushed down.
- Liquidity comes from recent sales pace, not from lifetime totals.
Step four: read the signal
- HoloScope estimate: the value the matching sales support.
- Deal Edge: (estimate minus ask) divided by estimate. Positive means listed below the estimate.
- Confidence: how strong the evidence is.
- Deal Score: the overall rating, from edge, liquidity, confidence, identity quality, market depth and stability.
What it cannot tell you
An estimate describes what comparable cards sold for. It is not a bid, and it is not a promise of what you could sell for tomorrow. Sales data can also be late or incomplete, which is why the ledger behind each estimate is on the page for you to check.
