#SWSH144Frequently asked questions
Is it worth grading Greninja V-UNION SWSH Black Star Promos SWSH156/307?
A PSA 10 currently sells for about £45.73, raw the card sits at £4.51 — 10,1× as much. Of 141 copies already graded, 60 % received a 10 and 25 % a 9. Mathematically, submitting returns £45.73 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. The grade distribution comes from the PSA Population Report; people pre-sort before submitting, so your own hit rate may differ.
What will I get for Greninja V-UNION SWSH Black Star Promos SWSH156/307 if I want to sell quickly?
Half of all sales fell between £4.40 and £5.62, with a median of £4.63. 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 Greninja V-UNION SWSH Black Star Promos SWSH156/307 unrealistic?
The cheapest genuine sales were around £4.38. Offers well below £2.63 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.
