The Product

From "what is this card"
to what it's worth — in one place.

Point your camera at a card and Hoshino identifies it, shows what it really sells for in every market, the difference between them net of fees, what each grade is worth, how rare it is, and what your whole collection is worth. Everything grounded in real, sourced data.

01 · Scan & identify

One photo opens the whole market.

Point your camera at a card or drop in a photo. Hoshino resolves the exact card — set, number and variant — then opens its real market, everywhere, on the next screen.

Camera or photo. No SKU typing, no set-symbol guesswork.
Exact match. The precise card, set and collector number — not a fuzzy name search handing you ten look-alikes.
Then the world opens. Every region's price, the difference and the grade math, one tap away.

Number #4/102

Rarity Rare Holo

Released 1999

Example scan · one confirmed card, every market one tap away.

02 · Real market price

Real market prices. Never asking prices.

An asking price is a wish. Hoshino shows what a card actually trades for in each market, side by side, so you read reality — not the most optimistic listing on the internet.

Sales, not listings. Every number is sales-derived and recency-weighted, so stale data fades.
Region by region. Every market we read, lined up together.
One honest median. No cherry-picked highs — the number you read is the number that holds.

03 · Cross-market differences

The same card, priced in every market at once.

Western trackers show you one country's price. Hoshino lines up every market side by side and shows the like-for-like difference between them — net of marketplace fees, shipping and live FX, so you're reading real numbers, not screen prices.

Every market, side by side. Lowest and highest, with the gap already worked out.
Net, not gross. Fees, shipping and live FX come out before any difference shows.
Like-for-like only. PSA 10 against PSA 10, raw against raw — never blended.

04 · Grade EV

What each grade is actually worth.

Grading ties up cash and weeks of turnaround. Hoshino shows the modeled value of a card at each grade — grounded in real graded sales, live population and current grader fees — so you can see where the value sits before you send anything.

Value at every grade. Raw, PSA 10, CGC 10, BGS 9.5 — the modeled market value of each.
Grounded in real data. Real graded sales, gem-rate baselines and 2026 fees — not a rule of thumb.
A read, not a promise. A modeled value, clearly labelled — Hoshino never guarantees a grading outcome.

05 · Population

How rare, really.

Scarcity should be a number you can see, not a feeling. Hoshino pulls live population counts from every major grader, so you know exactly how many of a card exist at each grade before you value it.

PSA · CGC · BGS · SGC. The four major graders' populations, in one view.
By grade tier. How many gem-mint, how many just below — the scarcity that actually moves price.
Feeds the value. Population is one input behind every grade read on the card's page.

352,000+ card pages

Every card has a page. Every page has the whole world.

The full catalog — Base Set 1999 to the newest release — with a public page per card: prices in every region, live asks from around the world, the trend, an outlook and the grading read.

World prices + live asks

Market price per region side by side, then the cheapest live listings on earth — with the difference against the benchmark already worked out.

Trend and outlook

The price path so far and a modeled outlook at one, three, five and ten years — with honest bands, not hype curves.

The grading read, on-page

GRADE, BORDERLINE or DON'T — the modeled call sits right on the card's page, before you buy it.

AI pre-grade

Know the grade before you pay

Snap a photo and Hoshino measures the card itself — centering, corners, edges — into a predicted grade, capped by the worst sub-grade the way real graders work. An estimate from your photo, never a guarantee.

The market taps you on the shoulder

Set a rule on any card — grade, region, platform, price ceiling — and Hoshino watches every market for it, in every currency, while you sleep. 5 rules free, unlimited on Pro.
