Frequently asked questions
Is it worth grading Grookey MEP Black Star Promos 052?
A PSA 10 currently sells for about $59.35, raw the card sits at $3.02 — 19.6× as much. Of 458 copies already graded, 88 % received a 10 and 12 % a 9. Mathematically, submitting returns $54.77 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 $5.29, across 198 fixed-price sales $6.86. 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 $4.03 and $8.18, with a median of $5.78. 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?
The cheapest genuine sales were around $3.00. Offers well below $1.80 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 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.
