Why Abacus
One comp isn't the whole decision.
Stop overpaying
Know the fair price for a slot or box before the timer forces your hand.
Pass with confidence
Walking away is a decision too. Make it knowing what you'd have paid.
Buy more of what's worth it
Every dollar you don't waste on a bad slot goes into a good one.
How it works
From asking price to answer.
Step 2
Compare
See it next to the sealed box and next to passing — fair range, fees, resale time, and how much to trust it.
Step 3
Decide
Buy, pass, or keep looking. Save the call, and when the outcome comes in, the next one gets sharper.
How we operate
What you can count on
You see what's behind the number.
Ranges show sales, assumed fees, and what it leaves out. We flag thin evidence - never made-up numbers.
We keep score on ourselves.
Every range gets checked against what actually sold. When we're wrong, the model changes.
The number isn't for sale.
Sellers, breakers, and marketplaces can't pay us to move a range.
Worth more than it costs.
Pricing and plans are designed to save you more than it costs so we win together.
About
Built by and with card collectors.

Abacus started as a spreadsheet Dylan built to price his own break slots in live auction rooms. It's being built into a product for the people making the same call every night.
