Frequently asked questions
Is it worth grading Grookey MEP Black Star Promos 052/0?
A PSA 10 currently sells for about $113.39, raw the card sits at $5.38 — 21,1× as much. Of 270 copies already graded, 87 % received a 10 and 13 % a 9. Mathematically, submitting returns $113.39 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.

Half of all sales fell between $4.59 and $9.98, with a median of $6.77. 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 052/0 unrealistic?

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.
