Every copy is worth the value you enter. Leave one blank and we fill it with our VGP Estimate, so the total up top always reflects everything you own. Every night at 11 PM EST we snapshot that total and add a point to your chart, recorded permanently — so have your values finalized by then.

The VGP Estimate is our market value for every game at every grade, built from real graded sales. We rebuild the whole grid daily, and it gets smarter every day — the more sales we log, the more games and grades have real comps behind them. Ungraded / sealed copies are valued conservatively, and for thin markets we fall back to comparably-rare games on the same console + grade. It is an estimate, not an appraisal.

Your value always wins — the estimate only fills in copies where you have entered nothing. Your line is only as accurate as the values you enter; the estimate only as deep as the sales behind it.
