What it does

Sold-comps price RANGE — the spread of recent eBay sold listings for that issue & grade. A range, not a single “this is worth $X” number — the market is a range.
Key-issue marker — flags well-known key issues so you don’t miss them.
Reprint / edition warning — a nudge to check first print vs. reprint/facsimile and newsstand vs. direct, which can change value a lot.

What it does not do

It does not promise one exact value, does not grade your comic, and does not replace your own checking. It points you at real recent sold data and what to verify. It collects no personal data and has no account.
