Why does grade-exact pricing matter?
A PSA 9 → PSA 10 jump can multiply value 5–10×. Generic tracking averages prices across grades, which is meaningless for an investor.
Can I track ROI per card?
Yes — enter your cost basis. We calculate ROI per slab and overall portfolio gain.
Which grading companies?
PSA, BGS, CGC, SGC, VGA, WATA and CBCS.
Is it free?
Free tier: 10 slabs. PRO ($2.99/mo) for unlimited + advanced analytics + CSV export.
