Is it worth grading Grookey MEP Black Star Promos 052?
A PSA 10 currently sells for about £44.39, raw the card sits at £2.26 — 19.6× as much. Of 458 copies already graded, 88 % received a 10 and 12 % a 9. Mathematically, submitting returns £40.97 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.
Auction or Buy It Now — which gets more for Grookey MEP Black Star Promos 052?
Across 136 auctions the median was £3.96, across 198 fixed-price sales £5.13. Fixed price therefore fetched about 30 % more — for this card patience with a set price is the better route.
What will I get for Grookey MEP Black Star Promos 052 if I want to sell quickly?
Half of all sales fell between £3.01 and £6.12, with a median of £4.32. 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 Grookey MEP Black Star Promos 052 unrealistic?

How does Last Sold determine the market value?
Last Sold 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.
