Frequently asked questions

Is it worth grading Champions Festival SWSH Black Star Promos SWSH296/307?

A PSA 10 currently sells for about $1,246, raw the card sits at $402.43 — 3,1× as much. Mathematically, submitting returns $1,246 on average, before fees and shipping. Rule of thumb: submit when the value at a realistic grade is at least double the raw value — which is the case here. Centering decides it: an off-centre card will not get a 10.

How does lastsold determine the market value?

lastsold uses only real sales — eBay plus auction houses like Goldin & Fanatics — recent sales count more (recency weighting), outliers and fakes are removed. It's not an estimate but actual sold prices, separated by condition, language and grading.
