Frequently asked questions
Is it worth grading Alolan Sandslash SM Black Star Promos SM18/248?
A PSA 10 currently sells for about £289.21, raw the card sits at £19.75 — 14,6× as much. Mathematically, submitting returns £289.21 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.
