# NonSportCardIndex

> Prices for graded non-sport trading cards, tracked card by card and
> grade by grade from live eBay listings and confirmed sales.

Every card in every set here has its own page for every grade it has
been found in. Three kinds of number appear and the pages say which is
which: asking prices from live listings refreshed through the day,
confirmed sales recorded only after a listing verifiably ends, and
estimated grades for raw cards assessed from the seller's photograph.

Where an accepted best offer means eBay never published what was
actually paid, the figure is shown as a ceiling with a less-than-or-equal
sign rather than as a price. Where there is not enough history to draw a
range, the page says so instead of drawing one.

## Understanding the numbers
- [Methodology](https://nonsportcardindex.com/methodology/): what an asking price, a confirmed sale and an estimated grade each mean, and why they are not interchangeable

## Browsing
- [Every card tracked](https://nonsportcardindex.com/browse/): the full index
- [Best value](https://nonsportcardindex.com/best-value/): cheapest entry into each card
- [Price drops](https://nonsportcardindex.com/drops/): asking prices that have fallen
- [Best deals](https://nonsportcardindex.com/deals/): listings below what the same card in the same grade has sold for

## What this index cannot see

- eBay returns at most 1,000 results for any search, however deep the
  paging goes. Several of the searches here match more than that, and
  because eBay sorts cheaper listings last, those are the ones that
  fall outside the window.
- A fixed-price listing has no end date, so this index learns one has
  gone by ceasing to find it rather than by watching it close. Most are
  re-checked within a day. Where one has not been seen for two days the
  page marks it and it is left out of deal comparisons.
- eBay never publishes what an accepted best offer actually paid, so
  those sales are shown as a ceiling with a less-than-or-equal sign
  rather than as a price.
- Estimated grades are this site's own opinion from a seller's
  photograph, not a grading company's verdict, and are labelled so.
