Every number here is real. Values are the figures from your own export; cost,
gain, ask and floor are computed from them with the spreadsheet's own pricing rules.
Nothing is simulated. What's missing is movement over time — that needs the
live sales feed, which isn't built yet.
On the real thing this is a Bluetooth gun or a phone camera —
it reads the cert off a slab or your barcode sticker off a raw card. Here,
type it. Same lookup, same answer. Press Enter to fire.
Going out — yours
Search and tap to add. Floor is the number that matters.
Coming in — theirs
Look the value up, type it once. Names you've entered
before will autocomplete.

Raw & Slabbed
What to ask, how far to come down, and when to walk.
Your cards are yours alone. Nobody else who signs in
here can see them — the database refuses to hand them over.
What this is
A card tracker built for standing at a table with a buyer in front of
you. It tells you what to ask, how far you can come down, and when to
say no.
It does not look up card values. It turns a value into a price.
Where the values come from is up to you — it reads exports from
Card Ladder and Market Movers.
Set this up first — in your tracker, not here
Enter your cards in Card Ladder or Market Movers. That is
where your values live, and every price on this page is worked out
from them.
Put a barcode sticker on every raw, ungraded card. A graded
slab already has a cert number printed on it — Card Ladder has a
field for it, so those scan as they are. Market Movers has no cert
field, so on Market Movers every card needs a sticker.
Type that barcode number into the card's Notes field.
Both platforms have one. That is what ties the sticker to the card.
Skip it and the card still prices fine — you just cannot scan it,
and at a show you will be hunting for it by name.
Then, here
Load your cards. Export to CSV, press ↑ Load export
and pick the files. Sold exports work too, and you can mix
platforms — drop them all in at once.
Look a card up. Pull the trigger on a Bluetooth scanner, or
type a cert, a barcode or a name. You get the ask in big type and
the rungs you can drop to.
Record what happens. Mark it sold, or build a trade with
cards on both sides and cash either way.
Cards you buy at a show can be added here by hand with
＋ Add a card. Nothing here talks to Card Ladder or Market Movers
— you press Export inside their app, and drop the file in here.
Housekeeping
Two things a list of card names cannot tell you, that the barcode can.
Worth a look after an import; not something you need at a show.
Backup and restore
Everything lives in this browser and nowhere else. Clear the cache,
switch phones, or open it somewhere new and it is gone. Save this file
somewhere you trust — and it is also how you move to another device.
Add a card
Only two things are required: what it is, and what it is worth. The
ask, the floor and the eBay prices are worked out from there.
What the numbers mean
Every figure on the page comes from two things you already have: what
a card is worth, and what you paid for it.
Where values come fromNot from here. This
app never invents or looks up a price — it takes what a card is worth and
works out what to ask, how far to come down, and when to walk. Keep your
cards in Card Ladder or Market Movers, and export from there.
Why raw cards need a stickerA graded slab
has a cert number printed on it, so a scanner can read it as it is. A raw
card has nothing. Put a barcode sticker on it and type that number into
the card's Notes field in your tracker — that is the link between
the sticker and the card, and it is what makes it scannable here.
ValueWhat the card is worth on the open
market. Straight from your export — nothing here changes it.
AskWhat to write on the card. It starts at
value and adds a markup, and the markup shrinks the further ahead you
already are — a card you're deep in the money on doesn't need a fat one,
a thin one does.
FloorThe number you walk away over. Below
it you'd rather keep the card than sell it. Every haggle rung and every
trade verdict is measured against this.
90% and 80% of valueRoom to come down. Any
rung that falls under your floor is hidden rather than shown, because
it's a price you refuse, not one you weigh.
Held, and the 90-day ruleInside 90 days
the ask defends what you paid. After that the protection expires and the
ask drops toward value — a card carried a quarter at a price nobody pays
isn't an asset, it's a brick.
At a show vs On eBayAt a table the price
is what you pocket. On eBay the fee and the postage come off it, so the
list price is grossed up and You keep shows what actually lands.
Serial numberedCards numbered out of a
small run. They're worth more and they trade far less often, so their
prices move slowly and are less certain.
Private modeHides what you paid, what
you're up, and your floor — so you can hand someone the phone.
