Is it worth grading Tapu Koko GX SM Black Star Promos SM50/248?
A PSA 10 currently sells for about £284.59, raw the card sits at £1.47 — 193,5× as much. Mathematically, submitting returns £284.59 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.
What will I get for Tapu Koko GX SM Black Star Promos SM50/248 if I want to sell quickly?
Half of all sales fell between £1.46 and £2.55, with a median of £1.93. Selling fast lands you nearer the lower end; with patience, good photos and a complete title the upper end is achievable.
Below which price is an offer for Tapu Koko GX SM Black Star Promos SM50/248 unrealistic?
The cheapest genuine sales were around £1.16. Offers well below £0.70 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.
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.
