Video game comps loose, complete, sealed or graded

The same title in four conditions is four markets, and the gap between them is often ten times. Completed sales are the only place that shows up.

Condition is the whole price

A loose cartridge, a complete in box copy, a sealed copy and a graded sealed copy of the same game can span an enormous range. Sellers say which in the title, so your search can separate them. Verified 12 October 2026: Zelda Ocarina of Time N64 returned 199 completed sales over three years.

Search narrow, not broad

This is the one category where search breadth genuinely matters. A bare console name across three years is an enormous aggregation for eBay's research backend and can fail upstream. Title, platform and condition is both more reliable and more useful: Ocarina of Time N64 complete rather than nintendo. If you do want a whole platform, use a shorter window.

Graded copies

WATA and VGA grades are in the title and come back parsed on each row alongside the grading service, so you can separate a 9.4 A+ from an ungraded sealed copy without string matching it yourself.

Offers and depth

Higher value games sell through accepted offers most of the time, and a public sold page reports the asking price on those. We return what was paid. And the 2021 sealed game bubble and its deflation are both inside a three year window and entirely outside a ninety day one, which is a good illustration of why depth matters here. Growth and above cover the full 1,095 days.
