#Market Values — How eBay Pricing Works

GamerVault automatically estimates the market value of every game in your collection using real eBay listing data.

💡 Want to quickly check a single game (no account needed)? Use the free Game value tool.

#How It Works

  1. Each game is checked against current eBay listings for the same title and platform
  2. Prices are split into three condition tiers: Loose, CIB (Complete-in-Box), and Sealed
  3. The average price is calculated based on active listings
  4. Your game's value is matched to the correct tier based on its condition

#Understanding Confidence Scores

Every price has a confidence score between 0 and 1:

  • 0.9+ — Excellent (50+ listings available)
  • 0.7–0.9 — Good (10–50 listings)
  • 0.5–0.7 — Fair (few listings)
  • < 0.5 — Low confidence (price shown but marked as estimate)

If confidence is below 0.5, the value is not used — your purchase price is shown instead.

#Condition Tiers

Condition Tier Example
Loose 1 Game cartridge only
CIB (Complete-in-Box) 2 Game + box + manual
Sealed 3 Factory-sealed

Your game's condition setting determines which price tier GamerVault uses.

#Why Prices Might Be Missing

  • The game is very rare (no recent eBay sales)
  • Platform or region mismatch
  • No price data has been fetched yet (prices update nightly)
