Collectibles marketplace intelligence

See it before it’s gone.

The best listings disappear in minutes. RareBlink watches the market around the clock — sports cards, Pokémon, TCG — understands what every card is worth, and alerts you the moment something worth seeing appears.

Screens shown with illustrative listings and data.

RareBlink continuously watches collectible marketplaces, identifies what is being listed, understands what it is worth, and alerts you when something worth seeing appears.

RareBlink never sells and never bids. It finds, values, explains — and hands you the listing.

Watches · standing orders

Tell it once. It never stops looking.

A Watch is a player, a set, or one exact card that RareBlink monitors around the clock — every new listing identified and valued against Recent Comps. You don’t need to know every card that exists. That’s RareBlink’s job.

A qualifying find becomes a Blink — and a Blink Alert, if you want one.

RareBlink Scan

Any card in your hand, valued in seconds.

Point your camera at a card — raw or slabbed. Scan identifies the exact card, parallel, and grade, estimates its RareBlink Value from Recent Comps, and offers to Watch it for you from then on.

Illustrative scan result.

RareBlink Value

An estimate that admits what it doesn’t know.

RareBlink Value is a fair-market estimate built from recent sold comps — and it always shows its confidence. When a card has no recent sales, RareBlink says so — no number is better than a wrong number. No implied precision. Ever.

Sold comps and asking prices are never mixed.

No sale comps — no value shown

No completed sales found — so RareBlink shows no value, and says why. A guess dressed up as a number helps no one.

Blink Alerts

Only when it’s worth seeing.

A Blink Alert is a push the moment a qualifying Blink appears. The urgency is the data — how far below market, how fresh the listing — never hype. You choose the threshold.

Fair questions.

Is RareBlink financial advice?

No. RareBlink Value is an estimate built from recent comparable sales — Recent Comps — with its confidence shown alongside it. It is not investment advice, and RareBlink never guarantees what any card will sell for. It’s information, presented honestly, so you can decide quickly.

Does RareBlink buy, bid, or sell?

Never. RareBlink is intelligence, not a marketplace. Every Blink links straight out — View on eBay opens the live listing, and anything you buy happens there, between you and the seller.

What’s the difference between Free and Pro alerts?

Timing. Both tiers see every Blink in the app the second it’s found — the live feed is never delayed for anyone. The difference is the push alert: Pro is notified the moment a Blink appears; Free is notified 30 minutes later. For cards that move fast, those 30 minutes are usually the whole game.

Do I need an account?

No. The free tier runs anonymously on your device — browse Blinks, set Watches, and Scan without signing up for anything. An account is only offered when it buys you something: syncing your Watches and Saved Blinks across devices, or a paid tier.

Where do the values come from?

From recent sold comps of the same card — sourced from licensed market-data providers — weighted by recency and match quality, with Value Confidence shown on every estimate. When a card has no sold comps, RareBlink shows no value at all rather than guessing; asking prices are never used to create a value. Sold comps and asks are never mixed.

Which marketplaces does RareBlink watch?

eBay today. RareBlink is built from day one to watch more collectible marketplaces, and new ones will be added to the app as we support them.
