Frequently asked questions
Is it worth grading Mewtwo SM Black Star Promos SM77/248?
A PSA 10 currently sells for about £4,932, raw the card sits at £32.96 — 149,7× as much. Of 1.127 copies already graded, 3 % received a 10 and 23 % a 9. Mathematically, submitting returns £424.71 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 Mewtwo SM Black Star Promos SM77/248?
Across 24 auctions the median was £13.33, across 114 fixed-price sales £13.36. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £9.57 and £15.42, with a median of £12.35. 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 Mewtwo SM Black Star Promos SM77/248 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.
