Get a pulse on the prices
Know what it's really worth—not what someone's asking.
Snap a graded slab and Cardium reads the label, finds the same card across every marketplace, and shows the price it actually clears at. No shill listings. No hopeful BINs.

From photo to real price in four steps
01
Snap
We read the set, card number, grader, grade and cert number straight off the label.
02
Identify
The cert number becomes a permanent ID, so we track this exact card—not a look-alike variant.
03
Converge
We pull sold comps from six marketplaces and strip outliers, relists and suspected shill sales.
04
Answer
One cleared price, with confidence and its plausible band attached.
